Attached file testcase
1. Load the testcase 2. Wait a few seconds (count shown on console should reach 30-50) 3. Quit Firefox Debug builds are too slow to reproduce the bug. I can reproduce reliably in nightly (opt) and asan+opt builds. bp-2d3069dd-9f30-45be-9e38-85af82140709 This seems to be a null deref, but since the testcase is similar to the one in bug 1002340 and bug 1022945, I'm making this bug private.
Attached file stack (ASan)
A null deref on shutdown doesn't sound too bad. Please adjust or clear the sec-low flag if it turns out to be bad.
Keywords: sec-low
Believed fixed by a bunch of MediaManager shutdown fixes jib and I landed in the last year (especially a bug that allowed MediaManager to try to restart during shutdown).
