It's strange that you can't reproduce it.  Perhaps when you type C-M-% on a
tty, it is interpreted as M-%.  But this bug happens only for regexp replace.

The cause of this bug are lines:

                            (and (or match-again
                                     ;; MATCH-AGAIN non-nil means we
                                     ;; accept an adjacent match.  If
                                     ;; we don't, move one char to the
                                     ;; right.  This takes us a
                                     ;; character too far at the end,
                                     ;; but this is undone after the
                                     ;; while-loop.
                                     (progn
                                       (forward-char 1)

that don't take into account the case when a read-only area is
adjacent to the next match, and skips it by (forward-char 1).
