I've done some research and found that terminate is called inside
gtk_main() from wxEventLoop::Run().
Changing it to:
try {
gtk_main();
} catch (int) {
puts("got it 3");
};
and running except sample never shows this debug message. Moving this
try..catch block to MyFrame::ProcessEvent in except.cpp caauses debug
message to be shown.
I am unable to debug GTK library to find exactly where throwed exception
stops.
I am using gtk 2.8.20

This problem is rahter critical and makes exception handling unusable.
They never reach OnRun for reasons unknown to me.
I checked 2.8.0 and today's HEAD and this problem still exists.
Any chance to resolve this in near future?
