You did not understand what I meant:

Qt is exception-safe only if compiled with -fexceptions. That is the=20
default.

But since it doesn't use exceptions on its own, it can be compiled with=20
=2Dfno-exceptions to save space (what I said before: the exception table in=
=20
libQtCore.so is larger than libglib.so entirely).

So you can expect people to compile it with -fno-exceptions. If you write=20
applications that rely on exceptions being enabled in Qt, you'll be=20
shooting yourself in the foot. Don't do that.
