5:54 p.m.
I got this backtrace (see below) when fontifying a Perl file. If anybody
is interested in the perl file, I can mail it. Let me know how I can
help further in fixing this.

The reason for the crash is that the 'text' member of the 'buf'
structure is null !
Here is the stack call by visual studio and below the lisp backtrace :

Fatal error.
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
Your version of XEmacs was distributed with a PROBLEMS file that may describe
your crash, and with luck a workaround. Please check it first, but do report
the crash anyway.
Please report this bug by invoking M-x report-emacs-bug, or by selecting
`Send Bug Report' from the Help menu. If that won't work, send ordinary
email to `crashes(a)xemacs.org'. *MAKE SURE* to include this entire output
from this crash, especially including the Lisp backtrace, as well as the
XEmacs configuration from M-x describe-installation (or equivalently, the
file `Installation' in the top of the build tree).
If you are fortunate enough to have some sort of debugging aid installed
on your system, for example Visual C++, and you can get a C stack backtrace,
*please* include it, as it will make our life far easier.
