[asterisk-dev] segmentation fault

[jonathan augenstine]

I have a problem that I am trying to track down and I need some input on how
to troubleshoot this issue.  I wrote a module that calls ast_app_getdata().
If there is a hangup during this call Asterisk throws a seg fault.  The
backtrace is below.  Any ideas on how to narrow down what the issue might
be?

Thank you for your help

Jonathan
