I would like to report the following bug.
Open the attached file in Emacs, and move point to the first position.
Define a keyboard macro: (I want to put each line inside double-quotes)
" ;; self-insert-command
C-e ;; move-end-of-line
" ;; self-insert-command
C-a ;; message-beginning-of-line
<down> ;; next-line
Now ask Emacs to repeat this macro 49 times.
The result is wrong: at around line 35, the first double-quote
is no longer at the start of the line; then on successive lines
the position of the first inserted double-quote walks to the right.

Thanks.
This is a duplicate of the (old, but unsolved) bug #13452. The
problem is not in beginning-of-line, it's in next-line: when the
window needs to scroll as result of next-line, point ends up in
columns 1, 2, 3, ... (i.e. gains one column per line moved down),
instead of sticking to column zero.
To work around, set line-move-visual to nil before running the macro
(or as part of the macro), then the problem goes away.
I'll try to debug this one of these days.

Hi Eli
Thanks for the swift response, and the explanation.

It seems that move-end-of-line and then forward-char achieves the right
thing (at least it did in a quick test).

Good luck!

But the above two calls are not a good replacement for next-line, they
produce different results.

I doubt that luck has anything to do with this ;-)

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