bug#2642: Apparent regression on font-lock-compile-keywords

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

====

I recently upgraded from Emacs 22 to Emacs 23 (W32 on Windows XP).
I have been using emacs-wiki and groovy-mode and not both fail with a similar 
error pointing to this:
font-lock-set-defaults: Wrong type argument: symbolp, (quote beginning-of-line)

It works on the second time or after turning font-lock on and off, and then 
fails again next time I try to use it.

If I enable debug-on-error I get:

Debugger entered--Lisp error: (wrong-type-argument symbolp (quote 
beginning-of-line))
  font-lock-compile-keywords(nil)
  font-lock-set-defaults()
  font-lock-mode-internal(t)
  font-lock-default-function(t)
  font-lock-mode(t)
  emacs-wiki-use-font-lock()
  run-hooks(text-mode-hook emacs-wiki-mode-hook)
  apply(run-hooks (text-mode-hook emacs-wiki-mode-hook))
  run-mode-hooks(emacs-wiki-mode-hook)
  emacs-wiki-mode()
  emacs-wiki-maybe()
  run-hooks(find-file-hook)
  after-find-file(nil t)
  find-file-noselect-1(#<buffer WrsTreeMap> "~/wiki/WrsTreeMap" nil nil 
"~/wiki/WrsTreeMap" ((256 5 . 48868) 204666627))
  find-file-noselect("c:/home/wiki/WrsTreeMap" nil nil nil)
  find-file("c:/home/wiki/WrsTreeMap")
  emacs-wiki-find-file(("WrsTreeMap" . "c:/home/wiki/WrsTreeMap"))
  call-interactively(emacs-wiki-find-file nil nil)

Looks like a regression to me - I saw a related discussion in one of the emacs 
supporting mailing lists.


=====

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/home/bin/emacs-23.0.91/etc/DEBUG for instructions.
