Hi!

I encountered a fatal error during an isearch-forward
within a several 10000 lines buffer.
Eventually it turned out that "size does not matter":
I was able to boil the problem down to a mere 3-bytes buffer
containing the letters "IAI".
If you place point just before the 'A', and then
do a "C-s C-w" sequence, xemacs dies from:

  Fatal error: assertion failed, file search.c, line 1487,
  (this_pos) > ((Bytebpos) 1) && this_pos <= ((buf)->text->z + 0)

instead of marking the "AI".
This occurs for example in today's cvs-head.
To be more precise, the assertion triggers for
CVS date-tag "-D 2007-08-27" and later, while it does not for "-D 2007-08-26"
Among the few files changed in that interval, it turned out
that revision 1.9 of "lisp/mule/latin.el" causes the problem
(or maybe makes an older problem evident).
I built my version of xemacs --with-mule.

Find below my system info (saw the same effect on
a redhat system as well, with the same build configuration).

regards,
Klaus

Warning:

Defaulting to the GNU Emacs-derived `sendmail.el' mail client. This facility,
while part of base XEmacs, is heinously underfeatured, and not going to get
better in the medium term. We include it so that bug reports work without
packages; we suggest that you choose and/or install one of the other mail
clients from packages if you're doing something other than M-x
report-xemacs-bug , or even if you are reporting bugs regularly.

To choose a package from those installed, click on "Options" ->
"Internet" -> "Compose Mail With ..." and decide on one from the
list. Gnus and VM are full-featured and have active user communities.

To disable this warning and stick with the old behavior, you can explicitly
initialize `mail-user-agent' to 'sendmail-user-agent .
