Compilation warnings and random crashes [message #60585]

I get a bunch of warnings like below when compiling on MacOS 10.15:

/Users/XXX/dvlp/cpp/code/upp/git/uppsrc/ide/RepoSync.cpp:283:6: note: use non-reference type 'Upp::KeyValueRef<Upp::String, int>'
        for(const auto& w : ~work) {
            ^~~~~~~~~~~~~~~

Basically, a reference is pointing to a temporary object.

And I'm getting random crashes with TheIDE when launching it on Linux (I'm not using a binary compiled on MacOS Smile

)

I guess, these crashes and references to temporary objects are related.

TIA

Regards,
Novo

VectorMap<String, int> work;

work is VectorMap ...

MapKVRange<AMap, K, T> operator~()                   { return MapKVRange<AMap, K, T>(*this); }

operator~() returns a newly created object.
So, compiler is right: you are referencing temporary objects ...

Novo

It is allowed. Range in for loop can be temporary.

Here is the disscussion (note that it discusses UB case, but U++ use is the first legal one):

https://www.sandordargo.com/blog/2022/04/20/range-base-p2012

I am currently testing with MacOS 14.5 and getting no such warning. Crashes in Linux are probably caused by something else.

Hi,

I think I can confirm Novo here.

TheIDE crashes frequently on linux (gtk), on the main package selection screen if I close a project and try to open a new one.

It appears to happen while TheIDE is trying to load the packages list.

I am using the nightly builds.

P.s.: One other point is, I don't get any crashes or warnings on debug builds. No matter how I tried, it just did not crash. (in release builds I get the invalid memory access error a lot.)

Best regards,

Oblivion

You mean completely close theide, then start it again? Or choose File / Open main package?

If the first one, does it depend on the interval between closing and starting again?

In both cases, does it crash without user inputs or do you do something?

What about release build with full debug info, started from gdb?

Hello Mirek,

It does not happen when I completely exit TheIdE. It only happens when I try to open another project. The package selection screen comes up and the app crashes (not always, but most of the time).

TheIDE on release mode (FULL_DEBUG flag) points to below line:

Thread 1 "theide" received signal SIGSEGV, Segmentation fault.
Upp::Image::Image (this=0x7ffffffe71e0, img=...) at /home/user/upp/devel/uppsrc/Draw/Image.cpp:295
295			data->Retain();

I hope this helps.

Best regards,

Excellent, that narrows it down probably to loading icons, but I bet there is a backtrace ("bt") ?

Can I ask for a little experiment:

ide/SelectPkg.cpp:671

	for(int i = 0; i < packages.GetCount(); i++) {
		const PkInfo& pkg = packages[i];
		Image icon = IdeImg::Package();
	/*
		Image icon = pkg.icon;
		if(IsNull(icon)) {
			if(pkg.main)
				icon = pkg.upphub ? IdeImg::HubMainPackage() : IdeImg::MainPackage();
			else
				icon = pkg.upphub ? IdeImg::HubPackage() : IdeImg::Package();
		}
	*/
		nest_list.Add(pkg.nest);
		clist.Add(pkg.package, DPI(icon, 16));
		alist.Add(pkg.package, GetFileName(pkg.nest), pkg.description, icon);
		alist.SetDisplay(alist.GetCount() - 1, 0, pkg.main ? bpd : pd);
	}

ide/SelectPkg.cpp:790

					if(d.ispackage && 0) {
						String icon_path;
						if(IsUHDMode())

Does it crash with these?

Done.
No crashes.Tried it ovew 30 times. Usually it should have crashed at my every 2nd or 3rd attempt.

If you need any more test, let me know.

Well, try to reactivate the first oneand leave the second one (... && 0)

And then maybe reversed Smile

What about (after reverting to master to remove both changes):

ide/SelectPkg.cpp:787

					if(d.ispackage) {
						String icon_path;
						if(IsUHDMode())
							icon_path = AppendFileName(path, "icon32x32.png");
						if(IsNull(icon_path) || !FileExists(icon_path))
							icon_path = AppendFileName(path, "icon16x16.png");
						tm = FileGetTime(icon_path);
						if(IsNull(tm)) // package icon does not exist
							d.icon = Null;
						else
						if(tm != d.itm || d.icon.GetSize().cx != DPI(16)) { // chached package icon outdated
							d.icon = StreamRaster::LoadFileAny(icon_path);
							d.itm = tm;
						}
						d.icon.Clear();
					}

(added d.icon.Clear to make it Null)

		Image icon = pkg.icon;
		RDUMP(IdeImg::HubMainPackage().GetSize());

****************** PANIC: Invalid memory access!

Weird...

What about

	for(int i = 0; i < packages.GetCount(); i++) {
		const PkInfo& pkg = packages[i];
		Image icon = pkg.icon;
		#define DD(x)  RDUMP(x.GetSize()); RLOGHEXDUMP(~x, min(32, int(x.GetLength() * sizeof(RGBA))));
		DD(IdeImg::HubMainPackage());
		DD(IdeImg::MainPackage());
		DD(IdeImg::Package());
		DD(IdeImg::HubPackage());
		DD(icon);
		#undef DD
		if(IsNull(icon)) {

As far I can see it is either

- compiler bug
- IdeImg is busted, but it is weird that it does not happen in the first iteration
- pkg.icon is busted, although this is hardly explains final crash in Image copy contructor (that AFAIK is call to Retain the data from Iml)

Another thing to try is

	for(int i = 0; i < packages.GetCount(); i++) {
		const PkInfo& pkg = packages[i];
		Image icon = Null; // <<<<<=============
		#define DD(x)  RDUMP(x.GetSize()); RLOGHEXDUMP(~x, min(32, int(x.GetLength() * sizeof(RGBA))));
		DD(IdeImg::HubMainPackage());
		DD(IdeImg::MainPackage());
		DD(IdeImg::Package());
		DD(IdeImg::HubPackage());
		DD(icon);
		#undef DD
		if(IsNull(icon)) {

Uh and please send the whole log - want to compare with "good run" (first invocation of dialog)

After a lot of thinking I believe that the only plausible explanation is that another thread calls Iml::Reset somehow.

Can you crash it and then send backtrace of ALL threads?

Also, can you try with this attempt at fix (but it would explain it just partly, still would like to have bt of all threads after the crash without the fix):

void Iml::Reset()
{
	for(IImage& m : map)
		m.loaded = false;
}

Tried but didn't fix it.

One interesting thing I've noticed is that the crash seems to be triggered in certain assemblies. But to be sure, it needs more test...

(maybe those specific assemblies have custom icons to display in package list?)

Anyway, from backtraces it looks like indexer/libclang is running full steam. Can you try with assist++ off?

Also, can you please update logging to:

https://www.ultimatepp.org/forums/index.php?t=msg&th=122 73&goto=61004&#msg_61004

and perhaps separately try setting Image icon = Null;

And the last obligatory question: It really is crashing only on opening new main package, right?

And BTW, when you test, do you test like for(;;) { Ctrl+M, Esc } or like for(;;) { Ctrl+M, select package, Enter } ?

Yes, while TheIDE is loading the main packages list.

Doesn't make any difference, TheIDE crashes after it switches to the package selection dialog.

However, I'm suspecting this is a compiler error now. (maybe O3 optimization level related?). I'll try other options (O2 and GCC), report back asap.

Well, clang got picky over unaligned access undefined behaviour, simply ignoring code like dword x[2]; dword y = *(dword )((const char *)x + 1); which caused some problems, but I think compiler error there would appear with some regularity. Irregular pattern like this is usually a race condition or uninitialised data...

Anyway, other things to try

	for(int i = 0; i < packages.GetCount(); i++) {
		const PkInfo& pkg = packages[i];
		DDUMP(IdeImg::GetCount());

Adding this log should might help to resolve whether IdeImg iml indeed gets damaged

And possibly

//		alist.SetDisplay(alist.GetCount() - 1, 0, pkg.main ? bpd : pd);

Comment display out, just to test if it is somehow related (the only other thing that does something with icons in the loop).

(Just to check whether maybe it is always the same package that causes problems)

Noticed something:

#2 0x00005555557a129f in IdeImg::Get (i=225) at /home/maldoror/Geliştirme/upp/devel/uppsrc/Draw/iml_source. h:113

If gdb gets it right, 225 is out of range. Which would be consistent with random crashes in release mode and probably a compiler bug.

Can you try

	DLOG("======== LOAD");
	for(int i = 0; i < packages.GetCount(); i++) {
		const PkInfo& pkg = packages[i];
		Image icon = pkg.icon;
		if(IsNull(icon)) {
			if(pkg.main)
				icon = pkg.upphub ? IdeImg::HubMainPackage() : IdeImg::MainPackage();
			else
				icon = pkg.upphub ? IdeImg::HubPackage() : IdeImg::Package();
		}
		nest_list.Add(pkg.nest);
		clist.Add(pkg.package, DPI(icon, 16));
		alist.Add(pkg.package, GetFileName(pkg.nest), pkg.description, icon);
		alist.SetDisplay(alist.GetCount() - 1, 0, pkg.main ? bpd : pd);
	}
	DLOG("~~~ LOAD");

Image Iml::Get(int i)
{
	DDUMP(i);
	IImage& m = map[i];
	if(!m.loaded) {
		Mutex::Lock __(sImlLock);
		if(!m.loaded) {
			m.image = MakeImlImage(GetId(i), [&](int mode, const String& id) { return GetRaw(mode, id); }, global_flags);
			m.loaded = true;
		}
	}
	return m.image;
}

If it really dumps out of range numbers in the loop, can you send me disassembly of void SelectPackageDlg::SyncList(const String& find) ?

Ok, I will do that later today.

But in the meantime I have found out that TheIDE compiled with GCC with the same level of optimization (O3) didn't crash, however I tried since yesterday (on the same machine/setup). Not once.
It does "appear" to be a compiler bug, but with the above tests -hopefully- we'll see.

Ok, I will do that later today.

But in the meantime I have found out that TheIDE compiled with GCC with the same level of optimization (O3) didn't crash, however I tried since yesterday (on the same machine/setup). Not once.
It does "appear" to be a compiler bug, but with the above tests -hopefully- we'll see.

Best regards,
Oblivion

I already have a workaround in the mind (just move image constants from inline to offline functions so that compiler does not try to optimise it), but frankly I am feeling pretty uneasy about bugged compilers...

Maybe we should move to gcc?

Hi,

I hope that 'moving to gcc' does not mean dropping support for clang.

My policy with platforms (including compilers) is to try to support more than one. When intermittent issues appear on one compiler, it is then easier to switch to another working compiler until the issue is resolved. When the code base is built to be compatible with MSC, CLANG and GCC (avoiding the known weak spots and/or bugs of each), the capability to handle new issues and avoid down time in such situations is far better.

Best regards,

Tom

Definitely not. Just swap preference in POSIX install script from clang to gcc.

if clang++ --version >/dev/null; then
	echo $UMK ./uppsrc ide CLANG -brs ./theide
	$UMK ./uppsrc ide CLANG -brs ./theide
	$UMK ./uppsrc umk CLANG -brs ./umk
else
	echo $UMK ./uppsrc ide GCC -brs ./theide
	$UMK ./uppsrc ide GCC -brs ./theide
	$UMK ./uppsrc umk GCC -brs ./umk
fi

if g++ --version >/dev/null; then
	echo $UMK ./uppsrc ide GCC -brs ./theide
	$UMK ./uppsrc ide GCC -brs ./theide
	$UMK ./uppsrc umk GCC -brs ./umk
else
	echo $UMK ./uppsrc ide CLANG -brs ./theide
	$UMK ./uppsrc ide CLANG -brs ./theide
	$UMK ./uppsrc umk CLANG -brs ./umk
fi

Still install both build methods. Also keep CLANG in win32 where we do have a control about clang version.

Hello Mirek,

I have attached the new logs.

Assuming that this is a compiler bug, I still wouldn't change the default on Linux. My reasons:

1) I didn't encounter it anywhere else. I have a lot of apps, tests etc, some have heavy inlining, and built with the same clang config. They are all stable (at least, they have yet to crash because of a really puzzling error.)
2) I tend to use ArchLinux on my machines (and other distros on VM), which ships the latest LLVM/clang, so this might be a bug in the latest version of the compiler. (At least, I did not have such crashes several months ago.)
3) GCC has significantly slower compilation speed.
4) I don't know of anyone else complaining about this bug, and I am fine with using the GCC build, it works as expected.

Best regards,

Oblivion

Yep, out of range...

What is clang --version?

Should we file this in clang's bugzilla?

I have also pushed a bunch of changes which I suppose should fix this. Can you try master?

If you mean commit 509e32c, I just tried it and no, unfortunately, TheIDE is still crashing with the same behaviour. Sad

At this point, yes.

Weird. Any chance of getting the .log?

That would mean isolating the issue into some small example, which we are still far from Sad

After digging deeper, I have fixed a bunch of errors related to handling non-existent files which in theory might fix the issue. Please retest master...
