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

Doesn't happen here.

Juanma, can you please post the translation of this to file names,
function names, and line numbers?  Thanks.

OK, Great. Perhaps a more recent build will have the fix.
With this build it is 100% reproducible (from `emacs -Q'), for me.

If it were not reproducible from `emacs -Q' I would not have sent
it, because the address starts with a "7", and I understand that
that means that the backtrace, at least, will be useless to you.

Nothing more happened here, apparently?  Or another debbugs glitch?

Dunno.  I think Juanma has been inactive wrt Emacs for a while now,
but he popped up again a while ago for a brief period.

My guess is that once again the info provided by the backtrace is
not helpful - just a guess, based on being told that for many other
backtraces...

Nothing can be done with this information.
