Subject: 24.3; previous-line, vertical-motion move too far with fci-mode on
Date: Wed, 29 May 2013 11:12:55 -0400

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':

----

Get a copy of Fill-Column-Indicator, e.g. with:

    git clone https://github.com/alpaker/Fill-Column-Indicator.git

Start Emacs with:

    open -n -a Emacs --args -Q --no-site-file --eval '(progn
(load-file "/path/to/Fill-Column-Indicator/fill-column-indicator.el")
(fci-mode t))'

You'll land in a `*scratch*` buffer with three lines of comments
followed by two blank lines, and the point will be on the last line
(line 5).

Call `vertical-motion` twice directly or indirectly:

    C-p C-p

or:

    M-: (vertical-motion -1) RET M-: M-p RET

Observe that the point moves from line 4 to line 2 on the second
`vertical-motion`.

I expect the point to move to line 3 rather than line 2.

----

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
/Applications/Emacs.app/Contents/Resources/etc/DEBUG.

Thanks.  This was reported a few weeks ago, see

  http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html

and was fixed in the development sources back then.
