I've encountered a big surprise for me.
My program doesn't catch any exception (in particully in main function ) when qt libraries have been included.
I googled this problem and didn't find an answer.
Please explain me:
1) Why this happens ?
2) How to bypass this ? I use a combination of libraries in software development (stl, boost, opencv) and i cant develop software, applying ONLY QT.
Details:
QT version - 5.2
Mingw 4.8 and 6.02
