This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
In XEmacs 21.2 "Dionysos" [Lucid] (i586-pc-linux) of Sun May 23 1999 on anton9.ida.liu.se
configured using `configure --prefix=/usr/local --with-xpm --with-xface --with-database=gnudbm,berkdb --with-xfs --with-png --with-gif --with-jpeg --with-tiff --dynamic=yes --site-prefixes=/usr/local/BerkeleyDB'
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
The following bit of elisp consistently causes XEmacs 21.2-b18 to dump
core. Enjoy:
(switch-to-buffer "FOO")
(insert "123456")
(defun acf (start end len)
(widen)
(goto-char 4)
(delete-char 1))
(let ((after-change-functions '(acf)))
(save-restriction
(narrow-to-region 4 4)
(transpose-lines 1)))
The idea is to delete the position where point is in the
after-change-functions. The above code works equally well when the
narrowed region is more than zero length and the delete-char is
replaced with a delete-region that deletes a region larger than the
restriction.
Configuration data, Lisp backtrace and C backtrace follow below.
