[Occasional crashes]webrtc::(anonymous namespace)::TaskQueueLibevent::Delete()

[dobeacon yang]

I'm running a process with webrtc integrated in Ubuntu, and it occasionally crashes as shown below. What's the reason? Has anyone encountered the same problem?

Is the crash related to a weak or disconnected network?

The condition for recurrence is: repeatedly creating and destroying peer connections

The webrtc version used is M86. The running system is Ubuntu 20.04.

crash stack is :
