bug#24692: 25.1; simple, reproducible Emacs 25.1 crash on MS Windows

[martin rudalics]

>> A simple recipe would be to run
>>
>> (defun foo ()
>>     ""
>>     (interactive)
>>     (let ((max-win-width  0)
>>           (max-win-height 1))
>>       (save-excursion
>>         (goto-char (point-min))
>>         (while (not (eobp))

Then put a message reporting ‘max-win-height’ in here.

>>           (end-of-line)
>>           (setq max-win-width  (max (current-column) max-win-width))
>>           (when (zerop (forward-line 1))
>>             (setq max-win-height  (1+ max-win-height)))))
>>       (cons max-win-width max-win-height)))
>>
>> on simple.el.  Does that crash?
>
> Yes.
>
> With emacs -Q, I visit simple.el and M-x foo crashes.
