 I don't know about Mac and can't test the code there right now but with
wxGTK except sample has the same behaviour so maybe wxMac has the same
problem, although I can't explain why would it happen there. As for wxGTK,
in 2.8 the code relies on undefined behaviour as it lets C++ exceptions
propagate through C code. This works just fine under Windows but doesn't
work under Linux at all (except for strings apparently but, again, I really
can't explain this). We fixed it in the trunk where the exceptions are
caught before the control returns to GTK+ code and the except sample works
fine there. Have you tried the trunk version under Mac?
