----------------------------------------

Thank you for your bug report. In order to move your issue forward, we require a backtrace[1] from the core file produced after the crash. Also, be sure you have DONT_OPTIMIZE enabled in menuselect within the Compiler Flags section, then:

make install

After enabling, reproduce the crash, and then execute the backtrace[1] instructions. When complete, attach that file to this issue report.

>   announce_join_leave = no
>   announce_user_count = yes
> ... run a 2+ participant conference.  Have "Leader" (marked) user drop call.  All guests kicked, as expected/specified.  Now dial back into the conf context.  Asterisk seg faults on READ command.
>  
> Same behavior if run as an AGI.
> Tested on 3 different servers, reproducible in all cases.
