The priority flag is not set for this bug.
:bryce, could you have a look please?

For more information, please visit auto_nag documentation.

Comment 3

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

Looks like a crash in IPC: https://searchfox.org/mozilla-central/rev/72e3388f74458d369af4f6cdbaeaacb719523b8c/ipc/chromium/src/base/message_loop.cc#377

Not sure if this is caused by media, searching https://firefoxci.taskcluster-artifacts.net/I_OEoi38Q9K6dzWie_CwRA/0/public/logs/live_backing.log for 'libxul' and looking for symbols, I don't see media stacks. So it could be a crash unrelated to the test.

Going to mark as P3 and we can look further if this crashes more.

Comment 4

[Firefox Bug Husbandry Bot]

Because this bug's Severity has not been changed from the default since it was filed, and it's Priority is P3 (Backlog,) indicating it has been triaged, the bug's Severity is being updated to S3 (normal.)
