next-line can move to the wrong column when point gets below the end of
the window.
The problem is in line-move-visual (i.e it only exists if the variable
line-move-visual is non-nil),
;; Otherwise, we should reset `temporary-goal-column'.
(let ((posn (posn-at-point)))
(cond
;; Handle the `overflow-newline-into-fringe' case:
((eq (nth 1 posn) 'right-fringe)
(setq temporary-goal-column (cons (- (window-width) 1) hscroll)))
((car (posn-x-y posn))
(setq temporary-goal-column
(cons (/ (float (car (posn-x-y posn)))
(frame-char-width)) hscroll)))))
If the position is not visible in the window, posn-at-point returns nil
and temporary-goal-column is not updated as it should.
