Andrew, ideas?

Comment 2

[Andrew McCreight [:mccr8]]

This looks like some kind of memory corruption issue. I guess it could be something else.

Do you get this crash regularly? Are you overclocking your computer or anything like that?

If you have steps to reproduce, please needinfo me. For now, I'm just going to dupe it to another existing issue.
