Looking at some old bug reports on XEmacs in Gentoo I found this
problem that is still present in 21.4.22.
The recipe is:
$ xemacs -q
M-x font-lock-mode RET
Paste this text below to the *scratch* buffer and evaluate it
'(("\\<\\(FIXME\\):" 1 font-lock-warning-face prepend)
("\\<\\(and\\|or\\|not\\)\\>" . font-lock-keyword-face)))
This results in the error message:
(1) (warning/warning) Error caught in `font-lock-pre-idle-hook':
This problem was in Gentoo reported also for 21.5.28. It seems though
that is has been fixed because with 21.5.34 I'm not able to reproduce.
Is this a known problem? Is it known to have been fixed for 21.5?
Would it possible to fix for 21.4 as well?
