Hi,
It seems you're right. qtdemo.exe crashes with segmentation fault too, so
it's not a Creator issue. The backtrace from gdb is different though.
Having spoken with a colleague it seems no one has built the very latest
version of QT 4.7 with MinGW, at least not without hacking Makefiles. I'll
switch to Visual Studio compiler and rebuild Qt and Creator.
Thank you for your help.
