bug#22226: 25.1.50; emacs_backtrace.txt

[Drew Adams]

This was from emacs -Q, and it is reproducible.  I did this:

1. M-x describe-categories
2. C-x 0 ; to remove the other, *scratch*, window.
3. M-> ; to go to eob.
4. M-v ; to go up one screenful.
5. M-v ; to go up another screenful.

Step 5 gave me the standard crash dialog box.

Exception 0xc0000005 at this address:
77417786
