My server is compiled with -O using the standard cc from SunOS 4.0.1.

For what its worth (which is not much), since I replied to your original
post about a week ago I have not been running xman and have not seen the
crash again. As far as I can recall that's about the only thing that has
changed in the set of Things I Run On A Regular Basis. Since you are
*not* running xman (and still see the problem, I presume) that means-
uhhh, I'm not sure *what* it means.

Neither did I.

I'm afraid not. And I'm as stumped as you are.  Since the problem seems to
have gone away for now and I don't know how to make it happen I probably
wont spend a lot of time looking at it. But I'd be glad to talk about it
and compare notes if you'd like to give me a call.
