More or less.  Fontification involves several passes.  A syntactic
keyword pass, a syntactic pass and a keyword pass.  In Emacs the
syntactic keyword pass will apply a verbatim face to the contents of
the verbatim environment.  In the keyword pass happening after that,
fontification will only be done if there is no verbatim face present.
But in XEmacs the syntactic keyword pass is not working (at least with
AUCTeX) and fontification in the verbatim environment cannot be
inhibited as the test for the verbatim face fails.

The backtrace I posted is not related to font locking.  It seems to be
a problem with shy groups in the regular expressions.
