All reviewed patches have been landed. Closing bug.
Since this patch landed the 64-bit GTK+ Debug bot has had random assertion failures in the FontCache code and general flakiness with respect to layout test font metrics. I think this patch might be the culprit. I've attached a stack trace of one of these failures.
Created attachment 72512 [details] Stack trace of recent GTK+ assertion failures
(In reply to comment #6) > Created an attachment (id=72512) [details] > Stack trace of recent GTK+ assertion failures Is "ASSERT(!lookupForWriting(Extractor::extract(entry)).second)" the assertion you reach? Do you see any code which changed behavior in this patch? Is this the only bug in the blame list?
