Description

On all platforms talos has been crashing with the following:

Commonly in cycle 9 on windows it seems but it does crop up in other cycles.

First windows incident: http://hg.mozilla.org/mozilla-central/rev/ba15a84af7e6
First linux incident: http://hg.mozilla.org/mozilla-central/rev/0dec4e077be2
First mac incident: http://hg.mozilla.org/mozilla-central/rev/ade1e110f6fb

So the earliest is ba15a84af7e6 but that is unlikely to be the cause I think.

Since there have been incidents on windows every day since the first I'd guess that the regression happened no more than a day before the first incident, which gives us something like:

http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2009-01-18+20%3A00&enddate=2009-01-19+20%3A00

It seems like bz's landings could be the cause of bug 474915 and bug 474938 so I suspect this could just be another expression of that.
