> As noticed on Jenkins during some gates it appears as though sometimes during bridging (be it simple or elsewhere) the cloning of a stream topology results in a crash. Why this is... is unclear.
> You can see it happening at https://jenkins2.asterisk.org/job/gate-ast-master-pjsip/370/ but I've also attached the backtrace and full log.
> It appears that an SDP negotiation is completing at the same time and the channel isn't locked - resulting in the topology being destroyed while being accessed.
