Michel R. Vaillancourt commented on ASTERISK-26973:
---------------------------------------------------

Ok, we're going to do some testing this afternoon and document the exact use-case that triggers the issue 100% of the time.

Once that is done, we'll start testing 13.13.0 to see what we get.  I'll report back with results.

> We upgraded one dev PBX and one production PBX to 13.15.0 and have discovered that suddenly a function that worked just fine before now causes Asterisk to SegFault.  Note that this ARI code function has been stable / safe for over a year;  the behavior began as soon as we upgraded.  
> Our DEV and PRD machines still running prior versions of Asterisk using the same ARI code do not exhibit this behavior.
