I know Jens has been touching WorkerRef nowadays...

I think Eden is a better expert here.

Comment 4

[Eden Chuang[:edenchuang]]

According to the crash stack, it seems to be a UAF on StrongWorkerRef of FetchStreamRead::mWorkerRef.
I am not sure if this is related to FetchStreamReader::mAsyncWaitWorkerRef.

I will look to see if there is a case that calls WorkerRef::Notify() twice on the same WorkerRef.

I don't see any intermittent happens after bug 1800659, it seems to be resolved with 1800659. Close this bug.
