Done, thanks.

%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.
