Hello guys,

I was trying to compile the latest TheIDE with MT to test the latest gdb_mi interface, but hit a strange error.
So I checked it with some other apps, and the U++ GuiMT example and always got the same result.

For example, with the GuiMT example I get the following errors, which seem to be the case for all MT apps (some part is in Turkish, but it can be translated as invalid expression before @indntpoff - thread local storage modifier for 32 bit architecture)

----- CtrlLib ( GUI MT GCC DEBUG SHARED DEBUG_FULL BLITZ LINUX POSIX ) (1 / 9)
----- CtrlCore ( GUI MT GCC DEBUG SHARED DEBUG_FULL BLITZ LINUX POSIX ) (2 / 9)

There were errors. (0:19.58)

So I produced the asm code of the relevant source files (heaputil.cpp and heap.cpp)
In heap.cpp, the code block that produce the error is like this:

LFE6366:
	.size	_ZN3Upp12MemoryShrinkEv, .-_ZN3Upp12MemoryShrinkEv
	.globl	_ZN3Upp16MemoryFreeThreadEv
	.type	_ZN3Upp16MemoryFreeThreadEv, @function
_ZN3Upp16MemoryFreeThreadEv:

	.cfi_def_cfa_offset 8
	.cfi_offset 5, -8

	.cfi_def_cfa_register 5
	subl	$24, %esp

	movl	_ZN3Upp4heapE@indntpoff, %eax                              <<------- gives error.
	addl	%edx, %eax
	movl	%eax, (%esp)
	call	_ZN3Upp4Heap8ShutdownEv
	leave
	.cfi_restore 5

	.cfi_endproc

_ZN3Upp11MemoryCheckEv:

	addl	%edx, %eax
	movl	%eax, (%esp)
	call	_ZN3Upp4Heap5CheckEv
	leave
	.cfi_restore 5
	.cfi_def_cfa 4, 4
	ret
	.cfi_endproc

Above code is the asm translation of heap.cpp, line 268+:

void MemoryFreeThread()
{
	heap.Shutdown();
}

void MemoryCheck()
{
	heap.Check();
}

In heaputil.cpp, the code block that produce the error is like this:

.LFE6353:
	.size	_ZN3Upp17PeakMemoryProfileEv, .-_ZN3Upp17PeakMemoryProfileEv
	.globl	_ZN3Upp13DoPeakProfileEv

_ZN3Upp13DoPeakProfileEv:

	leave
	.cfi_restore 5
	.cfi_def_cfa 4, 4
	ret
	.cfi_endproc

Above code is the asm translation of heaputil.cpp, lines 46+ and 302+:

void DoPeakProfile()                                      // Line 46
{
	if(sPeak)
		heap.Make(*sPeak);
}


...

MemoryProfile::MemoryProfile()                        // Line 302
{
	heap.Make(*this);
}

So the main culprit seems to be the "heap", which is defined as extern thread Heap in heapimp.h (see line 175):

extern thread__ Heap heap;

Any ideas on how to solve this problem? Is this a 32 bit i386 arch error only?
I can't compile any MT app with U++ heap. Note that they compile if I use USEMALLOC.

This happens on an ArchLinux with kernel 3.12 and GCC 4.8+ on a 32 bit AMD AthlonXP processor (without SSE2). I don't get this with an AMD 64 or newer Intel machines and I am using U++ nightly (6944).
