Using svn6883 on debian wheezy/sid

I don't know if this occur on other Linux distros:

The error (consistently) occur when:
1. I work on any package
2. I edit & compile this package 5 or more times
3. then a "invalid memory access" occur out of the blue and theide crashes
4. theide then continue to fail with this error when I try to reopen this package (it opens other packages ok)
5. theide only open the package again when I delete:
~/.upp/theide/cfg/packagename@mydevdirname.cfg, and
~/.upp/theide/cfg/*.cache
6. the above will occur with any package, regardless if from bazaar, uppsrc, examples, .., or one that I created

It is now so that I work for about 20 minutes & then above occur
and I need to do those deletions before I can work again for another about 20 minutes.

Any ideas, any help will be most appreciated.

Found this on tty1:
...
(grafix:11018): Gtk-CRITICAL **: IA__gtk_window_is_active: assertion `GTK_IS_WINDOW (window)' failed
(grafix:11276): Gtk-CRITICAL **: IA__gtk_window_is_active: assertion `GTK_IS_WINDOW (window)' failed
*** Error in `/home/slashupp/.upp/_out/mydevdir/GCC.Debug.Debug_Full.Gui.Mt.Shared.Sse2/grafix': corrupted double-linked list: 0x00000000026e0720 ***
(theide:11507): Gtk-CRITICAL **: IA__gtk_window_is_active: assertion `GTK_IS_WINDOW (window)' failed
...


('grafix' is one of my apps I just happen to be busy with)

ALSO: MOST SERIOUS:
I recompiled an app I wrote a while ago and is using constantly, with this svn6883 version and then used it for about 10 minutes before it also crashed with this error.
The old compiled executable (which I fortunately didn't overwrite) still works fine.
This means the error is somewhere in uppsrc and it gets propagated when compiling applications.

Hello slashup,

I also encountered the same kind of ide crash with a version compiled the 06/02/2014), so I just swithed back to my old version ( compiled the 6/12/2013 )

As for application crash, I am currently doing tests only, so no long time usage.

thx Didier

for confirming ... I will now also switch to the 6/12/2013 - version as that seems to be a ok one

PS: I (again) tried Qt, wxWidgets(with codeblocks) in the meantime, and
realized (again!) why theide is so much better for GUI-development.
(There just isn't any alternative once you started using theide, it spoils you - it's so easy, intuitive, right, )

EDIT:
seems the nightlies start at earliest 22 Jan 2014
is there a way I can get earlier versions?

Hello slashupp,

Can you describe your operating system. The main question here is do you use KDE?

Sincerely,
Klugier

debian 7

some KDE apps e.g. kdevelop, konsole, some games, kolourpaint, and
I guess some background run-times got installed as dependencies,
but not the full KDE.

There's some Gnome stuff as well, but again not the full Gnome either.

Same goes for LXDE.

I use LXPanel with openbox as my Desktop/WM. No session manager.

I've now installed 6806 (oldest I found) and have been using it for a few hours
now without the error occuring so far ...
If this keeps up then it would be safe to assume the cause of the bug was introduced in a later version


This morning won't open my package giving the error (sigh)
Problem gets propagated to generated executables as well

Cannot revert to stable 5485 on home-page: Sourceforge gives Server not found!

Hi,

I can confirm this same behavior: 'Invalid memory access' error + crash running the latest SVN.6937 (GTK) on Lubuntu 13.10 x64. I could recover from it only by:

rm 'main package'@'nest'.cfg

in ~/.upp/theide/cfg.

cat theide.log shows:

You can always checkout particular revision from svn. Recompiling ide is trivial (once you have some ide or umk compiled)

Well, I have not found a reason yet, but at least I now believe to have eliminated all those GTK errors popping in the console.

Maybe it will solve the problem. Please test (svn >6944) and report!

Hi,

I have now worked for about 15 minutes on the latest SVN.6947 64-bit TheIDE (Gtk) from this morning on Lubuntu. (This was installed from Honza's PPA).

While tracking compiler warnings on my own code, I crashed into a dialog with the following content:

Fatal error: Assertion failed in uppsrc/Core/Vcont.h, line 33

Hi,

I think there are probably two different problems:
  • crash in ide
  • crash in applications

I am saying this because of some observations I made:
  • ide still seems to be crashing (lattest posts)
  • apps don't seem to be crashing any more ==> a test I did this WE

One week ago, I just leaved my test application running and forgot about it (so I wasn't doing anything with it, nor with my computer) ... and it crashed all by itself.
I did the same test this WE and left it running all day while playing with it from time to time : NO CRASH

Hi,

I compiled a debug build for TheIDE x64 Linux SVN.6947 and then started it in debugger (F5). Now I have worked with it for about 6 hours without any problem.

I guess no news is good news in this case. I'll keep you posted if it crashes in one way or another -- although, soon I will need to switch back to Windows again...

Best regards,

Tom

Yesterday in the evening I had the same suspicious crash with theide like Tom1 on Ubuntu 12.04. I started several times and working time became shorter and shorter ( ca 1 min). I had a look at the crash report and saw that it was thread 1 (out of 3) in module Line Edit that produced this error.

I then switched tasks to cool down a bit but returned after an hour or so with the idea to run theide under the control of gdb. No crash anymore for a good hour of usage. Really strange ...

Well, you have 3 threads in theide?

That is really weird, current version is supposed to run single-threaded... (and it does for me).

Well an app that crashes when used mormally and that doesn't crash anymore when using GDB ... sounds like uninitialised var or data overflow ( array or something like that )

Actually, AFAIK, gdb does not influence these kinds of errors.

In theory it shouldn't but experience has showed me the contrary (many times).
I never looked into the precise reason but I guess the memory mapping changes du to the extra gdb libs loaded

Please note that I ran the DEBUG build in gdb. When I experienced the crashes, I was running a release binary from Honzas PPA.

Best regards,
