[Qt5-feedback] Qt5 and C++ exception

[joao.abecasis at nokia.com]

Even gcc / Linux has some issues with exceptions across shared library boundaries. They're related to symbol visibility and how exceptions classes are exported in each library in the stack trace. Such issues are also no fun tracking down...

Cheers,


João

While I generally like the concept of exceptions, those are quite tricky
with c++.

As Lars pointed out, dynamic libs and exceptions don't really mix well on
some platforms (for example, mixing msvc and gcc compiled exception-
enabled code will result in a unique kind of hell :) )

I'm not aware of non-windows os problems, but even if so, a large portion
of Qt users are on that platform.
