24.5; Positive argument to 'posn-at-point' throws erros as being negative |

Gnus/5.13 (Gnus v5.13) Emacs/24.5 (gnu/linux) |
To reproduce:
* Open a PDF on a separate window on the same frame using pdf-tools.
* Select that window.
* Scroll a bit down the first page of the PDF.
* Use windmove to move from the pdf-view-mode buffer to the first one.
With these steps, I get this backtrace:
Debugger entered--Lisp error: (wrong-type-argument wholenump -14)

hor (+ (or (cdr posn-cons) 1) (window-pixel-top window)) (+ (or (car posn-cons)
1) (window-pixel-left window))))
(cond ((and (numberp sign) (< sign 0)) (if hor (1- (+ (window-pixel-top
window) (window-pixel-height window))) (1- (+ (window-pixel-left window)
(window-pixel-width window))))) ((and (numberp sign) (> sign 0)) (if hor
(window-pixel-top window) (window-pixel-left window))) ((let ((posn-cons (nth 2
(posn-at-point (window-point window) window)))) (if hor (+ (or (cdr posn-cons)
1) (window-pixel-top window)) (+ (or (car posn-cons) 1) (window-pixel-left
window))))))
(let* ((frame (window-frame window)) (hor (memq direction (quote (left
right)))) (first (if hor (window-pixel-left window) (window-pixel-top window)))
(last (+ first (window-size window hor t))) (posn (cond ((and (numberp sign) (<
sign 0)) (if hor (1- (+ ... ...)) (1- (+ ... ...)))) ((and (numberp sign) (>
sign 0)) (if hor (window-pixel-top window) (window-pixel-left window))) ((let

direction (quote below)) (frame-pixel-height frame)) ((eq direction (quote
right)) (frame-pixel-width frame)) (t -1))) (best-edge-2 best-edge)
(best-diff-2 (if hor (frame-pixel-height frame) (frame-pixel-width frame)))
best best-2 best-diff-2-new) (walk-window-tree (function (lambda (w) (let*
((w-top (window-pixel-top w)) (w-left (window-pixel-left w))) (cond ((or ...

(setq best-edge-2 w-top) (setq best-diff-2 best-diff-2-new) (setq best-2

Note how the argument to posn-at-point (returned by window-point) is actually
positive (619194), but the error raised by Emacs complains about the number
being negative (-14).

OK, I'm therefore closing the bug (and the two merged with it).
People who think there are still leftovers are welcome to reopen with
details.
As for your questions about the semantics, I suggest to start a
discussion on emacs-devel.
Thanks.
