1.5.21 -- XEmacs becomes defunct while running?

[Ed Hirgelt]

I realize that this isn't the best of all possible bug reports.  But
it is the most information I have been able to get in the past few
weeks.

I've been plagued with a problem running XEmacs.  After a random
amount of time, running subprocesses fail with not a pipe. I have
never been able to find anything out about it. However, today I was
looking at pstree and noticed at some point that XEmacs dropped off of
the output.

Here's the sequence of ps before and after.  Note that I continued to
edit with XEmacs even after ps said it was defunct.

First, everything is more or less normal

Process 3980 is my XEmacs.  A little later:

You'll notice that 3980 is listed as defunct now.  At this point any
attempt to run a subprocess from xemacs fails. My last attempt
resulted in Opening pty or pipe: Invalid argument.

Exiting XEmacs and restarting works for a while but the problem
recurs. Nothing terribly intersesting is happening on the box other
than my running XEmacs, Eclipse, and Outlook.

Perhaps related, rxvt sometimes simply disappears out from under me
after a command, typically a bash script exits. No dump, no nothing.

Attached is cygcheck.out

Hope this helps someone.
