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 acknowledgement 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':



Create a file with many more lines than the buffer can display at once.

In my test, the buffer has about 500 identical lines like this:


123456789 0123456789 01234567890


Then place Point at line 1 column 1.


I recorded the keyboard macro that you see in Recent Input, which merely

moves point just past the first 9, then deletes it and puts an "x" in

its place for the first three lines.  Then it puts a "y" for the next

three.  Point is then moved to the start of the next line before the

macro is finished recording.


Play back the macro a few dozen times.


As Point keeps moving down, the buffer will need to scroll.  When it

does scroll, Point will not return to the start of the next line.


This happens also in version 23.4.1 on Win 7 and on 23.2.1 on Windows XP.


I guess the workaround would be to conclude the macro with C-u 0 l.


I'm amazed that I've been using Emacs (with macros) for 12.5 years and

never noticed this before!




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'.

Should be fixed now, please test the latest Emacs master branch.
