Subject: macros fail in emacs 23.1
Date: Thu, 24 Feb 2011 19:50:45 -0700

%emacs -Q
M-x version
GNU Emacs 23.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.22.0) of
2011-02-24 on hostnm01

<delete all text, so you are starting from an empty scratch buffer>

insert this line once (a <space> b):
a b

then copy it until the buffer contains 150 copies of that line:
a b
a b
a b
 .
 .
 .

ESC <                   ;; beginning-of-buffer
^X (     ;; start recording keyboard macro

C-s                     ;; isearch-forward
SPC                     ;; self-insert-command
C-e                     ;; move-end-of-line
C-b                     ;; backward-char
xyz                     ;; self-insert-command * 3
SPC                     ;; self-insert-command
C-a                     ;; move-beginning-of-line
C-n                     ;; next-line

^X )                 ;; end recording

^X e                    ;; run the macro one time
^X e                    ;; run the macro one time
C-u 1 5 0 ^X e          ;; run the macro 150 times

The expected outcome is that each line in the buffer should now look
like this:
a xyz b

But many of the lines still look as they did at the beginning, namely:
a b
.
Note that the incorrect lines are intertwingled with the
correctly-edited lines, up to the end of the buffer.

It looks like this bug report was submitted via bcc?
Please try not to do that, since if you do the bug tracking system has
no way of knowing which package (Emacs in this case) your bug report is
about. Or put "Package: emacs" at the start of the message body.

I have reassigned it to the emacs package. The full text of the original
report is below.

Something related to scrolling, it seems: the unedited lines start on
the second screenful.
