For what it's worth, a couple of us here got bitten by this every now
and then a couple of weeks back and it was on Opterons.  From what we
saw, it might have been dependent on the toolchain or something of the
like (although I hope it isn't).  I was building using Debian AMD64
stable and it would crash.  I upgraded to Debian testing and it went
away.  It started happening after c/s 11131 within about 100 changesets
or so.  It seemed really obscure and not widespread so we just moved on.

I hope this information helps a little.
