Yes, it's really getting funny.

21.4.16.  There was some discussion on the XEmacs lists about problems
with shy groups in connection with Gnus.  In this case the result was
a hang of XEmacs.  As far as I know this started with 21.4.16.  They
recently found a fix for that but I don't know if this will fix as
well the segfault I am seeing here.

It wouldn't be a big deal to disable the regexps in concern for XEmacs
in general, but if we get some feedback from the XEmacs people we
could probably disable them for affected releases only.

For XEmacs in general?
