23.0.50; set-frame-size problem(?)

[Vinicius Jose Latorre <viniciusjl@ig.com.br>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing 
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:



I'm not sure if there is a bug/problem with set-frame-position
or if I'm missing something.

Anyway, please, follow the steps below:

1. start Emacs:  emacs -Q

2. define and evaluate the following function:

 (defun my-frame-test ()
   (let ((mpos  (cdr (mouse-pixel-position)))
         (left  (frame-parameter nil 'left))
         (top   (frame-parameter nil 'top))
         (frame (select-frame
                 (make-frame
                  '((title          . ": TEST :")
                    (name           . ": TEST :")
                    (width          . 40)
                    (height         . 10)
                    (user-size      . t)
                    (user-position  . t)
                    (menu-bar-lines . nil)
                    (tool-bar-lines . nil))))))
     ;; if tool-bar-mode and/or menu-bar-mode is on,
     ;; the frame is positioned higher than it should.
     (set-frame-position
      frame
      (+ (or (car mpos) 0) left)
      (+ (or (cdr mpos) 0) top))))

3. turn on tool-bar-mode and menu-bar-mode:

M-: (tool-bar-mode 1) RET
M-: (menu-bar-mode 1) RET

4. position the mouse around the middle of the current frame.

5. now execute the function:  M-: (my-frame-test) RET
   Notice that the new frame is positioned higher than the mouse position.

6. kill the created frame and turn off tool-bar-mode and menu-bar-mode:

M-: (tool-bar-mode 0) RET
M-: (menu-bar-mode 0) RET

7. again position the mouse around the middle of the current frame
   and execute the function:  M-: (my-frame-test) RET
   Notice that now the new frame is positioned at mouse position.


Does anyone have this problem?
