I had that a few time but this is super rare.
Seems to be linux only

MOZ_DIAGNOSTIC_ASSERT(!IsDead()) seems to be used only in
https://searchfox.org/mozilla-central/source/dom/ipc/ContentParent.cpp

Comment 2

[Andrew McCreight [:mccr8]]

The lack of symbolication is unfortunate. The only diagnostic asserts we have for !IsDead() are in process switching code. This is probably a dupe of an existing issue.

Comment 3

[Nika Layzell [:nika] (ni? for response)]

I think this is probably a dupe of bug 1649092, which is symbolicated.

I'm guessing the crash reports are not symbolicated as the most common cause is due to an update wiping out the existing binary, and a content process startup crash due to a version mismatch.
