Random "Regular expression too big"

[Rob Emanuele]

Greetings,

Every now and again I've been getting an error "Regular expression too
big".  This seems to occur randomly.  Sometimes it can occur on
startup and emacs never opens.  Other times emacs opens and these
messages below are listed out.  Yet other times it'll happen in the
middle of my work while I'm saving, setting the fontset, or doing some
otherwise innocuous task.

This is with emacs:
GNU Emacs 22.1.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.12.5) of
2008-05-23 on xenbuilder2.fedora.redhat.com

This will still happen even if I remove my .emacs and even if I remove
/usr/share/emacs/site-lisp.

Thank you for any help fixing this or working around it!
