Sequence checker deadlock in M124 (Android)

[Dipankar Das]

Hi all,

On Android we are seeing a sequence checker deadlock issue while calling `detach()` at the very onset of the program. We have tried with NDK versions r25c and r27b but the issue remains. We are using webRTC version 124. Any help in this regard is highly appreciated.

Please see the stack trace below.

The Sequence checker fails to acquire the lock and it times out.

Thanks,

Dipankar.

Hi Dipankar - could it be that another thread holds the sequence checker? If so then this would happen but it also could be that there's a race in the code whereby detaching and re-attaching sequence checkers is not guaranteed to happen sequentially (without conflict).
