[Qt] Crashes with qt-4.7

As you mentioned redhat, I compiled on linux,
but does it really crash on linux ? 
I cannot reproduce it yet. I compiled Qt 4.7.1 (sse was 
enabled in .qmake.cache) and all just worked fine.

I did not find a way to detect in qmake and .pro 
that sse is set,to add -mstackrealign only when needed.

Reading the Qt source code it is apparently a windows mingw problem ??
