OK.. I originally thought this was some sort of AIX screwage.
It's been there since at least 21.2-b19 (I have a stack traceback from
Oct 29, 1999), but I've been seeing it under latest-CVS updated this morning
to -b46 plus. This on a RedHat 7.0 system.
Symptom: Using gnuclient, when you hit control-X # to close a client,
XEmacs folds up. Seems to be intermittent - today it's every 1-3 attempts,
but sometimes it won't bite for several days. Given that I'm seeing it
a lot, but it doesn't *seem* to be a show-stopper for others, I'm obviously
using some variant config that tickles the bug.
I've appended the Installation and tracebacks - anybody got any ideas?

Using Lucid menubars.
Using Lucid scrollbars.
Using Athena dialog boxes.
Using Athena native widgets.
Compiling in support for XIM (X11R5+ I18N input method).
- Using Motif to provide XIM support.
This (Motif for XIM but nothing else) looks like an odd combination.

FWIW, I'm using OpenMotif, but:

Using Lucid scrollbars.
Using Motif dialog boxes.
Using Motif native widgets.
Also, I have gnuserv use the currently selected frame rather than
opening a new one.
However, I've just run a quick test (with gnuserv using a separate
frame), and I get a similar crash:

Blame configure. ;) It found the Motif libs, so it used them...
OpenMotif?
OpenMotif 2.1.30-6 RPMs on the RedHat box, Motif 2.1 on the AIX box that
gets hit by the problem as well.
Additional info:
./configure --with-widgets=no --with-dialogs=no --debug=no --error-checking=none
--with-mule=yes '--cflags=-Wall -Winline -Wmissing-prototypes -Wmissing-declara
tions -Wno-switch -Wpointer-arith -Wno-sign-compare -Wno-uninitialized -Wshadow
-g -pipe -s'
will survive at most 3 invocations of 'gnuclient /etc/motd' (and usually
crashes on trying to leave the first try). Using --with-mule=no produced
an xemacs that survived 14 invocations before I got bored. I've now cycled
through alternate builds with mule=no and mule=yes 3 times, and it seems to
only crash on Mule builds.
Diagnosis: Motif and MULE don't get along. I'm not sure what level of
show-stopper it is - I may be the only bozo trying to build with both
Mule and Motif.
More additional info: --with=mule=yes --with-xim=xlib and Athena
widgets/dialogs works as well. Seems like the instant you allow Motif
to be linked in for *anything* (even XIM) it breaks Mule.
I've now exhausted my debugging ability on THIS one. Has *anybody* actually
had a working build with both Mule and Motif at same time?

That's reasonable. The help says:
--with-xim=xlib Compile with support for X input methods,
--with-xim=motif (*) Used in conjunction with Mule support.
Use either raw Xlib to provide XIM support, or
the Motif XmIm* routines (when available).
NOTE: On some systems bugs in X11's XIM support
will cause XEmacs to crash, so by default,
no XIM support is compiled in, unless running
on Solaris and the XmIm* routines are detected.
That clearly isn't true. I certainly didn't ask for XIM, but got it
anyhow. If anything, "xlib" should be the default.

Note: this doesn't seem to be specific to gnuserv; for me, "C-x 5 2"
then "C-x 5 0" causes instant segfault, with the familiar backtrace.

Nope; although I only use one frame, so I never noticed it until I
actually went looking.

widgets/dialogs works as well. Seems like the instant you allow Motif
to be linked in for *anything* (even XIM) it breaks Mule.
What about if you use Motif for everything *except* XIM?
I'm wondering if this has anything to do with the "VendorShell"
wierdness? This is one aspect of Xt I truly never got a handle on.
Both libXaw and libXm define vendorShellClassRec and
vendorShellWidgetClass. Past experience suggests that linking against
both can have odd consequences; the order in which the libraries are
specified in the link command can have an effect.

I tried and gave up. I had Motif trouble on both Solaris 7 (without
Mule) and Linux (with and without Mule, openmotif). Perhaps when
gtk-xemacs is stable enough the Motif support could be pulled entirely?

If we support Lucid and Athena, then supporting yet another Xt-based
widget set (i.e. Motif) isn't that much work. And I doubt if Xt
support is likely to be going any time soon (does GTK support multiple
displays yet?)
