Hi,
I have a problem with exception handling on Windows. In my application,
I set up a global exception handler with the function
Glib::add_exception_handler, so that this handler is supposed to be
called when an exception is thrown during the execution of the main
loop. It works fine when the program is built under Linux, but the
exception handler set up by Glib::add_exception_handler is never called
when the program is built under Windows.
I enclose a simple testcase. When clicking on the button:
- under Linux, the exception is normally catched in my_exception_handler,
- under Windows, the program terminates.
What's wrong? Thanks for your help.
