Well I bit the bullet, compiled with symbols and let dbx find the
problem for me. As usual, the Sun was chasing a null pointer that
presumably doesn't bother a Vax. I'm a little surprised this didn't
show up in testing on at least one of the non Vax machines.

I will include a diff of the fix. Its not clear to me how I submit
an Andrew bug report. If someone will tell me, I'll be glad to
do it.

    Fix for overhead/cwm/arbitrator.c
