Wireshark-dev: Re: [Wireshark-dev] Debugging an assertion failure

Hi Graham,

 

I’ve just tried ticking all the options under Debug -> Exceptions … but I still don’t catch it.  It’s strange because I’m sure I caused and caught assertion exceptions in the past.

 

Best regards…Paul

Hi,

 

I need some advice.  I’m debugging a problem with a dissector I’ve written.  Tshark fails with:

… \epan\prefs.c:414:prefs_register_module_or_subtree: assertion failed: (g_ascii_islower(c) || g_ascii_isdigit(c) || c == '_' || c == '-' || c == '.')

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

If I remove the dissector the problem goes away and so I’m sure it’s the cause.

 

Even though I can recreate the problem in a debug build under VS 2013 it doesn’t catch the exception.  I just see the above text flash by in the output command box.  How can I cause execution to break when it throws the exception?

 

Thanks and regards…Paul

 


I haven't tried this for g_assert() exceptions, but usually you need to open up Debug -> Windows -> Exception Settings and check more boxes.
