Hardware: Sun-4c/25
OS:	  SunOS 4.1.1
Epoch:	  4.0p1 + gravity fix from Chris Love
X Vers:	  X11R5p11

While operating an NCD X Terminal over a 19200 dialup using Xremote.

A core dump occured while doing a (set-window-configuration ...) of a
savd (current-window-configuration).

BTW: I have also been seeing screen update problems when doing this
kind of operation. A (recenter) clears the problem up.

I also had a core-dump like this (just yesterday) - Epoch 4.0p1 (no
fixes) X11R5p9 (I think) Sun cc, SunOs 4.1.1 using a Sun3 server (same
X11R5).	Not the same cause (was not doing a
(set-window-configuration)), but whatever happened, it resulted in the
same error: layout_window called on a bufferless window.  My core is
available for examination, but it looks very similar to that in the
above mentioned message.

cheers,
