Re: xemacs-beta crashs frequently

I tracked it down to `lookup-syntax-properties', if I set it to `nil' I'd get crashes when trying to scroll large-ish fontified buffers (usually cperl-mode). Try setting `lookup-syntax-properties' to `t' (if it's `nil') and see if that helps. Start with `xemacs -no-autoloads' and see if you can reproduce the crash with that. You probably won't be able to because I'm betting that it is font-lock related. Next, try with `xemacs -vanilla'. If you still can't reproduce the crash, eval each sexp in your ~/.xemacs/init.el until you can. Hopefully you know your way around gdb better than I do, so... $ cd /path/to/xemacs-build-dir/src/ $ gdb ./xemacs | tee /tmp/outputfile (gdb) run -vanilla eval that suspect form from ~/.xemacs/init.el in the "gdb started XEmacs" and then reproduce the crash. At this point come back to gdb and do `lbt' which'll give you a lisp backtrace. Do `bt' for a C backtrace. Now, unfortunately, this is where I get lost, but there are some gdb macros (already loaded into gdb because you started it from the src directory that has a `.gdbinit' file for this purpose) that you can use to inspect the values and names of the things in the C trace. I don't know if any of that will be of much help to you, but maybe it'll be enough to at least get you started. -- |---<Steve Youngs>---------------<GnuPG KeyID: A94B3003>---| | XEmacs - The only _______ you'll ever need. | | Fill in the blank, yes, it's THAT good! | |------------------------------&lt;sryoungs(a)bigpond.net.au&gt;---|
