[Bug: 21.4.19] XEmacs hangs at exit with "No such coding system: iso-2022-8"

(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) coding-system-property(iso-2022-8 pre-write-conversion) write-region(1 748 "~/.xemacs/history" nil quiet) savehist-save(t) savehist-autosave() kill-emacs() save-buffers-kill-emacs(nil) call-interactively(save-buffers-kill-emacs) ================================================================ System Info to help track down your bug: --------------------------------------- OS version: Microsoft Windows XP [Version 5.1.2600] OS: Windows_NT XEmacs 21.4.19 "Constant Variable" configured for `i586-pc-win32'.
