I got the following message when running auctex and doing a reformat
paragraph.


Fatal error: assertion failed, file regex.c, line 4569, VALID_CHARPTR_P (d)

Fatal error (6).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.

Please report this bug to the address `crashes@xemacs.org'.
*MAKE SURE* to include as much configuration information as
possible; at the very least what OS and hardware you are running
on, and hopefully also what compiler and compiler options the
binary was compiled with, what options XEmacs was compiled with,
whether you are using a prebuilt binary from ftp.xemacs.org or
compiled XEmacs yourself for your system, etc.

If at all possible, *please* try to obtain a C stack backtrace;
it will help us immensely in determining what went wrong.
To do this, locate the core file that was produced as a result
of this crash (it's usually called `core' and is located in the
directory in which you started XEmacs, or maybe in your home
directory), and type

  gdb /net/hg74/kooper/xemacs-beta/bin/xemacs-20 core

then type `where' when the debugger prompt comes up.
(If you don't have GDB on your system, you might have DBX,
or XDB, or SDB.  A similar procedure should work for all of
these.  Ask your system administrator if you need more help.)

Lisp backtrace follows:

  re-search-forward("[^\\\\]%\\|\n\\|\\'")
  # (unwind-protect ...)
  # bind (count)
  # (unwind-protect ...)
  # (unwind-protect ...)
  TeX-brace-count-line()
  # (unwind-protect ...)
  LaTeX-indent-calculate-last()
  # (unwind-protect ...)
  LaTeX-indent-calculate()
  LaTeX-indent-line()
  # (unwind-protect ...)
  # bind (justify-flag to from)
  LaTeX-fill-region-as-paragraph(1218 #<marker at 9960 in writeup.tex> nil)
  # bind (end start)
  # (unwind-protect ...)
  # bind (prefix)
  LaTeX-fill-paragraph(nil)
  # bind (command-debug-status)
  call-interactively(LaTeX-fill-paragraph)
  # (condition-case ... . error)
  # (catch top-level ...)

And dbx gave me
