Yes, there is a definate, confirmed composite segfault that I
bugzilla'ed.  Whether what you are seeing is the same, I don't know.
The crash I see is definately composite.

Eric's moving right now, and keithp won't be back until Monday,
so the easily reproducable crasher I bugzilla'd probably won't
get looked at for a bit.

No, I have it disabled now.  I wanted to get on with general testing.
