testcase

Testcase, reduced with 8mb stack limit (default on x86-64) and a cc1plus built
with a host gcc 4.3 compiler, just -g and checking enabled.

Reducing with 1mb stack limit now.

Try building without the patch but with unlimited stack (ulimit -s unlimited)

I can confirm, that indeed patch fixed this bug.
Yes patch bootstrapped and cross compiled and compiled the cross compiler and
native compiler ok, what I meant was this patch actually causes another new
regression/issues to surface. I am using the 64-bit x86_64-w64-mingw32-g++
binary on windows to compile qt4 what is happening now is that it will compile
qmake.exe just fine. As soon as qmake.exe is run ie, "qmake.exe
qt-all-opensource-src-4.5.2/src/plugins/accessible/widgets/widgets.pro  -o
Makefile -spec win32-g++" it crashes.
It should be another issue, should I make another bug report then?
You can close this bug as resolved.

Well, the patch may cause this issue, no?  Before the patch qmake
didn't build?  So I asked you to fix this bug by increasing the
maximum stack size and not by applying the patch to see if the patch
causes the qmake issue.

Or is there a reason the patch can't be the reason for the qmake failure?

Richard.

Actually can't try this because I'm using the native compiler to build qt4.(In

Well I think we have some misunderstanding here, initially it is cc1plus.exe
that crash g++ (native) built the
qt4 - qmake.exe      ok
    - qt4 src/core   ok
    - qt4 src/gui    failed (cc1plus.exe crashed)

> 
> Or is there a reason the patch can't be the reason for the qmake failure?
I think the patch should be the reason for qmake crash, but, before the patch I
tested with gcc revision 151400, now with gcc revision 151458 + patch applied.
Could this be the reason?

Yes, that could be the reason.  Can you test the same revision without the
patch again?

You mean cross compile the "native compiler" from linux by setting the shell
with command "ulimit -s unlimited" ?
Or you want me to build the cross compiler and native compiler then try and
build qt4?

This is under MSys/Mingw shell
$ ulimit -s unlimited
sh: ulimit: stack size: cannot modify limit: Invalid argument

Just the same way as you reported the bug (I understand that this
was a native compiler issue?).  There surely must be a way to increase
the maximum stack size with windows?

Ok there maybe a reason for qmake.exe crash, during the process, I changed the
O flag for building the qt4 library (before the patch in my script for building
qt4 -O0 due to that it will g++ will ICE see
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41153)) After the patch I changed
that from -O0 to -O2 and for qmake.exe changed from -O0 (I had to do this or
g++ will ICE) back to -O (original) because I thought that pr41153 does not
affect the gcc-trunk 4.5

Yes this was native compiler issue.
I have no idea on how to increase the max stack size with windows..

Ok I just found out that it is the -O and up causing the problem, I just
changed script back to -O0 and it compiles and runs fine, right now up to
corelib.

To increase the stack size on windows, add -Wl,--stack=0x20000000 (for eg 32 Mb
 stack).  This hard codes the exe's stack size into the program header.

------- Comment #31 from t66667 at gmail dot com  2009-09-09 09:08 -------
Sorry about the delayed testing.
With the same gcc revision (without patch applied) and with
"-Wl,--stack=0x20000000" as suggested by Danny.
cc1plus.exe still crashed while running the following command.

g++ -c -include tmp\obj\release_static\qt_gui_pch.h -pipe -O0 -m64
-Wl,--stack=0x20000000 -Wall -frtti -fno-exceptions -DQT_THREAD_SUPPORT
-DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_BUILD_GUI_LIB -DQT_NO_USING_NAMESPACE
-DQT_NO_CAST_TO_ASCII -DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT
-D_USE_MATH_DEFINES -DQT_NO_DIRECTDRAW -DPNG_NO_ASSEMBLER_CODE
-DQT_RASTER_IMAGEENGINE -DQT_RASTER_PAINTENGINE -DQT_NO_CUPS -DQT_NO_LPR
-DQT_HAVE_MMX -DQT_NO_FREETYPE -DQT_NO_OPENTYPE -DQT_NO_STYLE_MAC
-DQT_NO_STYLE_GTK -DQT_NO_STYLE_WINDOWSCE -DQT_NO_STYLE_WINDOWSMOBILE
-DQ_INTERNAL_QAPP_SRC -DQT_NO_DEBUG -DQT_CORE_LIB -I"..\..\include\QtCore"
-I"..\..\include" -I"..\..\include\QtGui" -I"tmp\rcc\release_static" -I"tmp"
-I"..\3rdparty\wintab" -I"..\3rdparty\libpng" -I"..\3rdparty\zlib"
-I"..\3rdparty\harfbuzz\src" -I"dialogs" -I"..\..\include\ActiveQt"
-I"tmp\moc\release_static" -I"." -I"..\..\mkspecs\win32-g++" -o
tmp\obj\release_static\qwidget.o kernel\qwidget.cpp
So in conclusion, qt4 library compilation complete with -O0 and
"fix-fld-recursion" patch applied to gcc. With -O the compiled qmake.exe will
run crash, comment #14.
