Hi Stephen, Vin,
Thanks for your responses. I've managed to build xemacs with the
debugging on. I've attached the installation report once more.
These are somethings you might want to know:
1. Interestingly, my xemacs does not support (?) M-x report-xemacs-bug!
I really don't like to use the menu, but, then, I also noticed that
"Send Bug Report" from my help menu is disabled.
2. Reproducing my crash is simple. I just bring up xemacs, and exit.
This crash happens just as xemacs is exiting.
3. Another interesting thing: This crash does not occur when I follow
this sequence:
o Start xemacs
o M-x (I get into the mini buffer)
o C-g (Quit the mini buffer)
o C-x-c (Quit xemacs)
4. The crash occurs if I get into the mini-buffer with a C-s (for a
search), and then C-g, C-x-c
5. Off topic, but, I am not able to build xemacs with a "--with-gtk". I
get into some compiler error complaining undeclared GTK_TYPE_GDK_EVENT
in when compiling device-gtk.c. Nothing related to the problem at hand,
could possible be due to the co-existense of both gtk-1.2 and gtk-2.0 in
my machine; I'll look more into it before I pass on the cake to you. If
this is a known problem, you could possibly tell me where I've gone wrong.
Thanks for all the efforts in making xemacs strong. I've never worked
with xemacs; and I find the editor is having wonderful features. I am
getting late, and my next mail would be after about 12 hours.
Regards,
Arvind.

The goal is an XEmacs that is impossible to crash from inside. It may
be triggered by your customizations but we still want to fix it!
FWIW, the stack trace makes no sense at all to me (those functions
just shouldn't be calling each other, and there's only one "real" Lisp
function, the other Ffunctions() are all redisplay "glue") suggesting
that the stack has been smashed, or that gdb is very very confused.
I note you're using Motif on Solaris 5.6; that Motif is known to have
bugs which can cause crashes (but the symptoms are quite different
from your report). Sun has made patches available, see our PROBLEMS
file for details if you're not sure your system is up to date.

setnu, at least, is now packaged; if you have the edit-utils package
installed, you can just get rid of that code. cscope I'm not sure
about; I've heard of it but it doesn't seem immediately available from
my XEmacs (I know I need a separate binary, but the Lisp bindings
should be visible and they're not).

Please give a more precise description of what you're doing when you
crash, too. Did you click on a GUI element, or drag a scroll bar?
Were you typing? If so, what? What mode were you in? Does it seem
to be aassociated with certain files? etc etc
Finally, a convenient feature: M-x report-xemacs-bug will give you a
formatted bug report buffer, containing Installation, information
about your installed packages and loaded features, and the last few
strokes typed (not very useful with a crash, of course, but can be
very useful if you experience a non-fatal bug). If your environment
permits you to send mail from XEmacs, you can send it with C-c C-c,
otherwise you can save it to a file and attach the file.
