posn-at-x-y reports wrong window |

I received the bug report below for our visual-line-mode in Aquamacs
Emacs, but I managed to reproduce the core issue on Emacs 23 (Nextstep
port) as follows:
(fringe-mode 0)
C-x 3 C-x 2 C-x o C-x o
(we're now in the large window on the right, with two small windows in
the left half of the frame).
Insert enough newlines to be vertically just above the horizontal
divider on the left.
M-: (posn-at-x-y 0 (cdr (posn-x-y (posn-at-point)))) RET
Insert newline, now we're next to the divider line.
M-: (posn-at-x-y 0 (cdr (posn-x-y (posn-at-point)))) RET
--> wrong window (the window in the upper left) is given in the
structure.
Instead of 0, the x value can be up to 6 ((frame-char-width) reports 7).

Subject: [Aquamacs-bugs] visual-line-mode error with vertically
split windows
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
THE SETUP: vertically split window with the left half split
horizontally. This is commonly used in, say, ECB, perhaps other modes:
---------
| 1 | 3 |
| | |
----| |
| 2 | |
| | |
---------
THE BUG: in the right hand window, attempting to move the cursor (in
column 1) through the row adjacent to the mode line of the upper left
hand window moves the cursor to the upper left window. Also, placing
the cursor in column 0 of that row then typing C-n or C-p gives the
error "Position not in text area of window."
TO REPLICATE:
C-x 3 C-x 2
Hit return in the right side window (3) enough to get you past the
divider
on the left.
Then C-p back past the divider. Cursor jumps to upper left window (1).
Now click on the row in window 3 adjacent to the divider. Type C-n or
C-p. Gives above error.
