--- Comment #31 from t7 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=0x2000 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=0x2000 -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 -Itmp\rcc\release_static -Itmp -I..\3rdparty\wintab -I..\3rdparty\libpng -I..\3rdparty\zlib -I..\3rdparty\harfbuzz\src -Idialogs -I..\..\include\ActiveQt -Itmp\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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41254

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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41254

Before the patch qmake was built and running ok. 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. 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/guifailed (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.

To increase the stack size on windows, add -Wl,--stack=0x2000 (for eg 32 Mb stack). This hard codes the exe's stack size into the program header.
