1166920 - frequent crashes when typing quickly in Google Doc

Status: RESOLVED DUPLICATE of bug 1166277

(Core :: JavaScript Engine, defect)

Description

[Luke Wagner [:luke]]

On the latest Nightly, I was able to crash 5 times pretty quickly in GDocs.  It seems to involve typing quickly (typing slowly has no crash) and using undo.  I was able to repro in a large doc and a new, empty doc.  3 of the crash reports are in GC store buffer tracing:

https://crash-stats.mozilla.com/report/index/74b987cb-f9d8-4a84-9150-d79442150520
and 2 are in MacroAssembler under storeUnboxedProperty:

https://crash-stats.mozilla.com/report/index/3c77a41d-d94c-400c-a373-892742150520
which makes me think this is related to unboxed objects.

These crashes are probably dupes of bug 1166700 and bug 1166277.

Looks fixed in current nightly.
