Crash Data

It started spiking in 19.0a1/20121018 and is currently #2 top crasher in today's build. The regression range is:
Bug 802144 is my best guess.

I'm doubtful that it's related to 802144. I'm more inclined to look at some of Matt's patches that landed in that range.
This isn't obviously caused by anything I landed, unless it exposed an existing bug somehow.

Looks like this affects windows with BasicLayers only.

Can't see how we're getting a crash address of 0x8 either, neither FrameLayerBuilder::mInitialDOMGeneration nor nsRootPresContext::mDOMGeneration are at that offset.
I'm fairly sure this is a duplicate of bug 803826. Undupe if I'm wrong.

It's not because it stopped in 19.0a1/20121020 before the patch of bug 803826 landed. The working range is:
