Dear Bug Team!
My 21.5 windows build crashes with the following recipe:
xemacs -vanilla z.el
z.el contains:
(defun remove-block (header footer)
"Remove the block of text delineated by header and footer."
(goto-char (point-max))
(let* ((s (search-backward header (point-min) t))
(e (search-forward footer (point-max) t)))
(and s e (kill-region s e))))
(find-file "/tmp/gnuclient-test")
(insert-string "
(setq package-get-package-index-file-location
\"e:\\XEmacs\\XEmacs-21.5-b28\\etc\")
")
(goto-char (point-max))
(remove-block "\n;;; Lines added by gnuclient_setup\n" "\n;;; End of
gnuclient_setup addition\n")
M-x eval-current-buffer and boom! Note that the search should fail.
My lisp is a little rusty and I could easily have made a mistake in
the remove-block routine, but I don't think a crash should occur.
Note that 21.4 behaves as expected.
Lisp backtrace follows:
# (unwind-protect ...)
# (unwind-protect ...)
# (unwind-protect ...)
# (unwind-protect ...)
# (unwind-protect ...)

footer (point-max) t))) (and s e (kill-region s e)))
# bind (footer header)

It's easy for me to reproduce this and I can poke around in the
debugger to answer any questions.

Warning:
Defaulting to the GNU Emacs-derived `sendmail.el' mail client. This facility,
while part of base XEmacs, is heinously underfeatured, and not going to get
better in the medium term. We include it so that bug reports work without
packages; we suggest that you choose and/or install one of the other mail
clients from packages if you're doing something other than M-x
report-xemacs-bug , or even if you are reporting bugs regularly.
To choose a package from those installed, click on "Options" ->
"Internet" -> "Compose Mail With ..." and decide on one from the
list. Gnus and VM are full-featured and have active user communities.
To disable this warning and stick with the old behavior, you can explicitly
initialize `mail-user-agent' to 'sendmail-user-agent .
