I don't catch exception in Qt

[Petin]

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

        QApplication a(argc, argv);
        throw "ex";
    }
    catch(...)
    {
        // Do Nothing
    }
    return 0;
}

Hi
Qt should not have any effect your your ability to use exceptions.
Tried your sample on win 10 , vs 2015 compiler and it works.

@mrjj I don't have any problem with exception, if i don't include and don't apply Qt library. I use Qt creator 3.0.0 and windows 7. Can you advise me, where start to research this problem ?

@Petin
When you dont "apply Qt library. " can it be its other compiler or
setting that is being used ?
What compiler are you using ?

@Petin, does your program run correctly if you don't throw an exception?
