      Status: Waiting for Feedback  (was: Triage)

This may be the cause of your crash but is not the actual problem. If it's NULL then something has gone quite wrong. Please provide a backtrace showing this and more information about what is going on at the time.

> Getting :
> ERROR[30921][C-00004648]: atsobj2.c:116 INTERNAL_OBJ: user_data is NULL
> From looking at where INTERNAL_OBJ is called, I noticed that on line 339 of astobj2.c (Asterisk 13.2.0) that the obj object returned from INTERNAL_OBJ is not checked for NULL, but still used. This could be causing our crash. I also checked the latest build and this occurs on line 342 of astobj2.c 
> Crashes at least once a week.
