Dear Bug Team!
Remember all those bug reports about XEmacs 21.5 crashing on perl
or C files (mostly the reports were from me)? I've dug into it a bit
further and have discovered that the culprit is
`lookup-syntax-properties'. If you set that to `nil' you get the
crash. Here's the recipe:
xemacs -vanilla
In the scratch buffer, eval `(setq lookup-syntax-properties nil)'
Visit a large-ish C or perl file (I used 'src/emacs.c')
Do `M-x font-lock-fontify-buffer RET'
If XEmacs doesn't crash at this point, just scroll through the file
and it will.
Does it crash without -vanilla? For me, I can reproduce this exactly with
vanilla, but with my regular setup, it does not crash. At first I suspected
the progress meter, because I have had long ago crashes with it running.
So I turned it off in scratch before trying the rest of the commands and got
the same crash (in the xemacs -vanilla)
My autoload requires are
(require 'saveplace)
(require 'saveconf)
(require 'recent-files)
(require 'pending-del)
(require 'filladapt)
(require 'psgml-html)
some variables I have set usually are
(setq buffer-file-coding-system-for-read 'raw-text)
Custom set
'(font-lock-mode t nil (font-lock))
I don't see any others that might affect the outcome, unless it is screen
geometry or tab setting.
