Yes, building Gnus with XEmacs 21.5 gets around it, and _that_ Gnus
seems to work OK in XEmacs 21.4 too.

Seems that we've (XEmacs.org) screwed things royally.  Who's big on
syntax tables that could take a look at this?

The only things that I could find that might be remotely related
are... 

2003-02-28  Ben Wing  <ben@xemacs.org>

  [...]

	* chartab.c (fill_char_table):
	* chartab.c (put_char_table):
	* lrecord.h:
	Fix crash due to attempt to free objects across dump/undump.

This patch is at:

<http://list-archive.xemacs.org/xemacs-patches/200303/msg00000.html>


And...

2003-02-14  Ben Wing  <ben@xemacs.org>

	* buffer.c:
	* syntax.c:
	Move syntax table description from buffer.c to syntax.c.
	
	* chartab.c:
	* chartab.c (set_char_table_dirty):
	* chartab.c (fill_char_table):
	* chartab.c (Fmake_char_table):
	* chartab.c (Fcopy_char_table):
	* chartab.c (get_range_char_table_1):
	* chartab.c (get_range_char_table):
	* chartab.c (put_char_table):
	* chartab.h:
	* chartab.h (struct Lisp_Char_Table):
	Free extra char table entries to avoid excessive garbage.
	Add flags for dirty and mirror_table_p to char tables.
	Add a back pointer from mirror tables to the original syntax table.
	When modifying a syntax table, don't update the mirror table right
	away, just mark as dirty.
	Add various asserts to make sure we are dealing with the right type
	of table (mirror or non-mirror).
	
	* font-lock.c:
	* font-lock.c (find_context):
	* syntax.c (init_syntax_cache):
	* syntax.c (setup_syntax_cache):
	* syntax.c (mark_buffer_syntax_cache):
	* syntax.c (init_buffer_syntax_cache):
	* syntax.c (syntax_cache_table_was_changed):
	* syntax.c (update_syntax_cache):
	* syntax.c (scan_lists):

	* syntax.c (update_just_this_syntax_table):
	* syntax.c (update_syntax_table):
	* syntax.c (vars_of_syntax):
	* syntax.h:
	* syntax.h (struct syntax_cache):
	Add entry to syntax caches for the non-mirror table.  Set it
	appropriately when initializing the syntax table.  Use it, not
	the mirror table, for calls to syntax_match().
	Don't create a bogus float each time, just once at startup.
	Add some asserts, as in chartab.c.

	* syntax.h (SYNTAX_CODE_FROM_CACHE):
	When retrieving the syntax code, check the dirty flag and update
	the mirror tables as appropriate.
	Add some asserts, as above.

This one is here:

Thanks very much for getting back to me on this, Katsumi, I really
appreciate it.  BTW, do you know enough about these kind of things to
take a look at these two patches and perhaps offer some suggestions?
