[Kde-bindings] Fixed the QDialog.Exec() crash on Windows

[Dimitar Dobrev]

Strictly speaking, it is a fix in Qyoto - this -mstackalign flag should be added in the CMake scripts somewhere.
You don't need to build a debug version of Qt - each binary installation (either Qt SDK or Qt libraries) contains two sets of files Qt<name>.dll and Qt<name>d.dll (for example, QtGui.dll and QtGuid.dll). This "d" means "debug" and signifies the library is a debug build. I got my stack trace using an installation of Qt libraries 4.8.0.

So was that a fix in Qyoto or in Qt?

Good work finding this...I hope I can figure out how to debug low-level crashes like this, so I can be more useful in this effort.  Looks like I'll have to build a debug version of Qt itself :-)

I tracked the problem down to qt_blend_argb32_on_argb32_sse2, which, according to http://svn.netlabs.org/qt4/ticket/187, is fixed by simply compiling everything with the -mstackrealign GCC flag.
