> Using Siren7 codec throws a segfault at random times during a call. THe Endpoints involved are different Polycom IP6000 and IP7000 phones

> At the time of the crash, several Polycom endpoints were using this asterisk instance with siren7 codec in parallel. The typical usage scenario is that those endpoints are participating on app_conference based conferencing, and transcoding is happening for those endpoints (siren7 -> slin16)
> This problems occurs in guesstimated 1 out of 20 calls, and minutes to hours after the call has been established
> I can make core dumps available if helpful
