Hi,

The message you pasted is the one MSVCRT's abort() prints (unless you _set_abort_behavior), so setting a breakpoint there should trigger at g_assert failure. https://msdn.microsoft.com/en-us/library/da5kh0wa(v=vs.120).aspx tells me you can press ctrl+b for that.

Regards,

Ahmad

Hi Ahmed,

 

Thanks for the suggestion.  How do I break on abort()?  The assert seems to disappear into glib and abort is part of stdlib.

 

Best regards…Paul

Hello Paul,

 

You could always put a breakpoint on abort(). There is surely some way to configure VS2013 to catch it, but this might be the wrong place to ask about that.

 

Best regards,

Ahmad

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
