In analyzing the backtrace, the regression may have been introduced by patch [1] to fix bug 1398483. [1] https://hg.mozilla.org/mozilla-central/rev?node=6c1bb0f3ff98
Flags: needinfo?(miyer)
MOZ_CRASH Reason: MOZ_RELEASE_ASSERT(!mAllocatedPointers.Contains(aPtr))
I don't see any new (de)allocations in bug 1398483, so it seems unlikely to be the culprit. Note that this diagnostic assertion was added fairly recently so it might show up as a regression even though the underlying issue is older.
Not allocating anything new in bug 1398483 as Mats noted so most likely not related.
Flags: needinfo?(miyer)
There have been no new crashes since the 5 on the June 30 build.
Given that crashes have stopped, resolving. Please reopen if this starts up again.
