We're now seeing this on the Thundebird builders quite frequently. Unfortunately I'm not quite sure how far it goes back.

The stack there is a bit shorter:

I'm pretty sure this is unrelated. The bug I filed is about broken Alpha as in http://en.wikipedia.org/wiki/DEC_Alpha, not alpha as in before beta.
