This bug was filed from the Socorro interface and is report bp-02c5ca94-847a-4fc5-b3cc-2764a2170328. ============================================================= This crash is new in 53 beta 5 and showed up on the explosiveness report: http://bit.ly/2mMvJsV All the crashes seem to be confined to Mac OS and affects all versions of Mac OS. Not sure which component this belongs in - I just made my best guess.
Does anyone know why this doesn't have a crash reason annotation?
As phillip pointed out this has not been seen after Beta 5, so we can close it out if it doesn't reappear.
IPC was a reasonable start, but I looked at a half dozen of these and they all have stuff like mozilla::dom::PContentChild::Read(nsTArray<mozilla::dom::ServiceWorkerRegistrationData>*, IPC::Message const*, PickleIterator*) in the stack, so this is or was some service worker issue, I think.
From the array, I'd guess this is the PContent InitServiceWorkers message.

It looks like we only annotate in the parent process, but this was from the child process .  https://hg.mozilla.org/releases/mozilla-beta/annotate/62467dd7218f/ipc/glue/ProtocolUtils.cpp#l302
Ooh, we should fix that! That probably dates from the days where crash annotations in children were main-thread-only.
