             Summary: bridging: Sometimes cloning the stream topology causes a crash
                 Key: ASTERISK-27692
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27692
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Bridges/bridge_simple
    Affects Versions: 15.2.1
            Reporter: Richard Mudgett


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.
