Windows 7 64bits host, using compiler Visual C++ 2010 SP1 (16.00.40219.01)
Description
When giving the "-ltcg" parameter to "configure.exe", the produced x64 binaries in release mode are crashing upon startup when calling Qt5Gui.dll.
Message got by profiling from Dependency Walker:
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.
This occures with GUI examples, designer, assistant and probably any program using Qt5Gui.dll.
