Someone else recommended I remove the -fstrength-reduce; I did and it
didn't help.  Your note makes it nearly certain that this has nothing
to do with it.  (Did you use -O?  What release's cc?)

Curious.  I don't think I've run xman even once under R4.  I suppose it
must be something that both xman and one of my clients do....

And someone at MIT did comment, saying something about we'd have to
narrow down the search space.

Yes, thanks, that's what I wanted to do.  I didn't really expect "we'll
drop whatever we're doing and get on it right away".  But I have no
idea where to look.  I don't know which pieces of the server are
getting exercised during the crash sequence; I was hoping someone could
tell me, which is why I described the sequence in the detail I did.  I
could insert a call to my checking routine every third line throughout
the server, but that's extremely tedious and overly drastic.  I was
hoping rather for something like "look at foo() and bar() in
dix/foobar.c, or anything in dix/blee.c".

I guess I'll have to wing it.  Steve, I don't suppose you have Internet
access by any chance?
