Exception handling doesn't work with Qt on Windows

Question

I\'m facing strange problem. Namely, Qt somehow turns off exception handling in my program. I can\'t catch any exception, and when I throw an exception application crashes.

Answer 1

I've reconfigured and recompiled Qt with flag -exceptions:
D:\Qt\2010.05\qt>mingw32-make confclean && configure -exceptions && mingw32-make
and now everything is ok!

Thanks all for help, especially to Nick D!

Anyway, it's very strange that I had Qt build without this flag. I had downloaded Qt SDK in binary form from official site.
