Bill, do you see any way we can debug this? Could it possibly help you with any of the GC bugs?

It looks like a patch I have in my queue may be triggering this semi-reliably.

How often does it seem to happen, and what platforms? Also, what's the patch that's triggering it?

Also, does anyone know if there's a bug on file to get minidumps from tryserver? I've heard there was one, but I can't find it.

Actually, looks like it was a bug in my patch.  It went away when I fixed a different issue.
