Subject: 24.3; Introduction to Elisp 14.3: count-words-defun misbehaves
--text follows this line--
This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

I used C-xC-e to evaluate the functions count-words-in-defun and
count-words-defun as displayed in the Info section 14.3 of the
Introduction. I then used C-xC-e to set the key sequence C-c= to invoke
the latter function. I then positioned point in the sample function
provided to see whether the two count-words functions were correct.
Instead of reporting that there were 10 words or symbols in the
function, Emacs reported that there were 1 word or symbol and point was
moved to the beginning of section 14.3. Point should not have been moved
in that fashion, according to the Introduction.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.3/etc/DEBUG.
