> Asterisk Segfaults during stress testing against ConfBridge. It seems to be triggered by a combination of admin/marked and nonadmin/unmarked joining and leaving a single conference.
> It is easily reproduced using SIPP with 100 calls. I've included the dialplan but essentially 100 calls are generated, half use an admin profile and the other half a participant. They are randomly joining 64 bridges for 30s and it crashes every time.
> Program terminated with signal 11, Segmentation fault.
