Hello Tom, can you please take a look at this?
There are also this type of failures: https://treeherder.mozilla.org/logviewer?job_id=371641038&repo=mozilla-central

Set release status flags based on info from the regressing bug 1750298

I am having a hard time understanding how this is even possible. It seems like mPipeOut must be null in CloseAndRelease, but that should only be the case when we already ran that function before, which mStreamClosed again should prevent.

https://hg.mozilla.org/mozilla-central/rev/ef3985b77a7b

Matthew do you have any ideas what is going on here? Maybe this is some sort of re-entry problem, because we don't set mStreamClosed at the top? I think this caller is causing crashes: https://searchfox.org/mozilla-central/rev/f8db81665dc2833fff09dc7eef200539ac1fd351/dom/fetch/FetchStreamReader.cpp#99

This is probably a reentrancy problem.

Looking at this crash report I see in the backtrace that we're doing WeakWorkerRef notification. That means CloseAndRelease is likely being called via the lambda here.

The lifecycle issues around how worker shutdown works and how the FetchStreamReader is destroyed has always been confusing to me. I think asuth has a better idea; ideally if we could get this recorded it would be very helpful.

We may want to consider backing this out just because of the frequency

Changing the priority to P2 as the bug is tracked by a release manager for the current nightly.
See Triage for Bugzilla for more information.
If you disagree, please discuss with a release manager.

:mgaudet The null check patch seems to have solved the problem here, is this still something we need to consider backing out considering the frequency ?

No, I think this can stay doesn't need backout. We can resolve this particular bug as fixed, but I'll open a followup bug to clarify lifecycle here and cleanup here.
