[Interest] Trouble with "release" build on Win7

[Yves Bailly]

Greetings all,

I'm building Qt5 for 64bits using Visual 2010 on a Windows 7 64bits host, debug and release.

However it seems anything using Qt5Gui.dll fails to start.

- Running the example qtbase/examples/gui/analogclock/debug/analogclock.exe works fine.
- Running the example qtbase/examples/gui/analogclock/release/analogclock.exe fails.

Trying to "profile" the exec using Dependency Walker, it ends by this message:

DllMain(0x000007FEEFF50000, DLL_PROCESS_ATTACH, 0x000000000018F700) in 
"d:\libsrc\qt-5.0.0-x64\qtbase\bin\QT5GUI.DLL" called by thread 1.
First chance exception 0xC000001D (Illegal Instruction) occurred in 
"d:\libsrc\qt-5.0.0-x64\qtbase\bin\QT5GUI.DLL" at address 0x000007FEF01E4FC0 by thread 1.
Second chance exception 0xC000001D (Illegal Instruction) occurred in 
"d:\libsrc\qt-5.0.0-x64\qtbase\bin\QT5GUI.DLL" at address 0x000007FEF01E4FC0 by thread 1.

The same occures when trying running any GUI program, e.g. "assistant" or "designer".

Any idea about what I could check or try to find the issue?

My "configure" command was:
configure -confirm-license -opensource -debug-and-release -c++11 -shared -ltcg -accessibility 
-qt-sql-sqlite -plugin-sql-psql -opengl desktop -qt-zlib -qt-pcre -icu -qt-libpng -qt-libjpeg 
-qt-freetype -no-angle -no-incredibuild-xge -openssl -no-qml-debug -mp -I %ICU_INCLUDE% -I 
%OPENSSL_INCLUDE% -I %PGSQL_INCLUDE% -L %PGSQL_LIBS% -L %OPENSSL_LIBS% -L %ICU_LIBS%

Any hint much welcome.
