How to catch bad_alloc (or other exceptions) on Linux? Topic is solved

[geralds]

How do I catch exceptions thrown from the main application frame (the MyFrame class in my case)? On XP this works fine but on Linux I get a segfault (the exception just isn't caught).

Where can I find an example that shows me how to get around this?

Thanks!

Can't you use a debugger? for segfaults it's usaully very straightforward in IDEs

[Radioation]

have you tried calling

::wxHandleFatalExceptions( true );

and overriding

wxApp::OnFatalException?


I think the "except" sample in the samples directory shows how to use it.


I believe I've used it in the past and it worked for my segfaults, I don't have anything using it right now. std::bad_alloc should be able to be caught in an ordinary catch() statement, I've got code that currently does that.


Outside of wxWidgets I've used sigaction() to set a signal
handler for SIGSEGV (and some other signals).


If you're gettting segfaults, you are better off finding the cause in a debugger and making sure they don't happen.
