(Sorry if this is a duplicate of what I sent directly from XEmacs, but
I've never done e-mail within XEmacs and so have no idea whether my
attempt to send a report directly from there actually worked.)
Dear Bug Team!
I try to exit XEmacs 21.4.19 under Windows XP by either using the main
window close button or menu item File > Exit XEmacs.
The minibuffer shows message
No such coding system: iso-2022-8
and XEmacs will not exit. (The only way I can exit is by using the
Windows Task Manager.)
At first I thought this was caused by AUCTeX, but AUCTeX expert David
Kastrup says the problem is "very clearly an XEmacs-internal" one that
has no particular relation to AUCTeX.
Here's what C-h v kill-emacs-hook RET says:
`kill-emacs-hook' is a variable declared in Lisp.
-- loaded from
"e:\acs\software\XEmacsWindowsKit\xemacs-21.4-2006-01-28\lisp\subr.elc"
Value: (save-place-kill-emacs-hook savehist-autosave
#<compiled-function nil "...(16)" [bookmark-alist featurep bookmark
bookmark-time-to-save-p t bookmark-save] 2>)
And here's what I get from
M-x set-variable RET debug-on-error RET t RET
Debugger entered--Lisp error: (error "No such coding system" iso-2022-8)

Actually, the problem is not XEmacs-internal. It's due to a library
that was coded by somebody who assumed that Mule facilities are always
available, but XEmacs 21.4 on Windows doesn't support Mule well, and
it's almost never available in that configuration.
The included patch should work. To test without patching and
recompiling, you can put the following form in your init.el:
(setq savehist-coding-system
(if (featurep 'xemacs)
(if (fboundp 'find-coding-system)
(or (find-coding-system 'utf-8)
(find-coding-system 'iso-2022-8)
;; support --with-file-coding
(find-coding-system 'binary))
;; drop back 15 and punt!
'binary)
;; assume Emacs 20, at least
'utf-8))
Please let me know if that does work for you. If so, I'll apply it to
CVS and we should have a package release in short order.
If you do decide to apply the patch locally, it will not interfere
with future upgrades of the package in any way (but if you upgrade
"too soon" you'll lose the patch). Don't forget to recompile with M-x
byte-compile-file.

New subject: [PATCH packages] [Bug: 21.4.19] XEmacs hangs at exit with "No such coding system: iso-2022-8"
That addition to init.el fixes the problem. Thank you!
I won't try to patch and recompile locally, since I have never before
compiled XEmacs from source. For now I'll leave the fix in init.el and
wait for the new package to be released.

The one I just posted is improved (I now understand better what the
code is doing so I'm actually willing to commit it ;-), and it uses a
direct test for the needed function instead of a generic test for
Mule).
Sorry about dropping this on the floor ... just too much in my queue
these days.
