We get this failure about 2 times per day on macosx1500-aarch64-shippable/opt-xpcshell-1 jobs in bug 1839361. The logs show repeated crashes for test_ext_background_early_shutdown.js where the crash dump has no thread list stream (e.g. repeated 10 times):

This seems followed by the same issue for xpcshell-remote.toml:toolkit/components/extensions/test/xpcshell/test_ext_storage_session.js, except that this one eventually succeeds to run, e.g.:

I doubt that the tests themselves would be the cause for the failure, so this likely belongs in a different component.

Hi :willdurand, can you confirm if in your opinion these failures are filed in the right component right now, and if not where they might fall? Thanks!

Hi :willdurand, can you confirm if in your opinion these failures are filed in the right component right now, and if not where they might fall? Thanks!

yes, both those tests are covering WebExtensions internals and so the bugzilla component is the right one for being investigated on our side.

As a side note: both the tests (test_ext_background_early_shutdown.js and test_ext_storage_session.js) are simulating crashes and are supposed to prevent the crash triggered on purpose by the test case themselves to be reported as failures, and so we should look if there have been changes that are making those crash to appear to be failures (or if the way the test is trying to prevent that is being racy and it fails to prevent the crash triggered on purpose from being reported as a failure).
