So the general scenario in this bug is:
- RemoteWorkerChild on the "Worker Launcher" thread in a content process is receiving a delete message.
- This results in DestroySubtree being invoked for the RemoteWorkerChild which recursively destroys child actors before their parents.
- PFetchEventOpProxy is managed by PRemoteWorker, so we expect FetchEventOpProxyChild instances to be destroyed before we reach this point.
- Async "returns" IPC methods like PRemoteWorker::ExecServiceWorkerOp do not result in actors being created, but instead a std::function resolver lambda is created that uses an MFBT (non-thread-safe) WeakPtr which the lambda checks on entry so that it can ensure the actor is still alive. (So there's no destruction; it just turns into a no-op.)
- The RemoteWorkerChild::ActorDestroy method is calling
mTerminationPromise.RejectIfExists(NS_ERROR_DOM_ABORT_ERR, __func__);
- mTerminationPromise is used by:
- ServiceWorkerOp termination ops so they can resolve on termination.
- Non-termination ServiceWorkerOps where when they bounce to the main thread to dispatch their runnable to the Worker they find that the worker is no longer
Running
.
- There's a null access...
The disassembly at the point of crash looks like:
