[Qt-creator] QtCreator crashes in debug build

[Paweł Rutka]

Hi
I have some trouble to run QTCreator debug build. I have build 4.6 branch (
previously 4.5 too) with Qt 5.10 and mingw delivered in Qt on Windows 7.
All the time I got such stacktrace:

qtmain_win.cpp     104  0x40a5c5
17 main
               0x41059d

SIGSEGV was received.
I do not know exactly where to go from here, maybe its Qt 5.10 bug and
someone already heard about it (I cannot find any refernce about it).

Thx for all help !

Regards,
Pawel
