Subject: 24.0.50; bidi; emacs crashes with SIGABRT
Date: Sat, 11 Dec 2010 14:32:17 +0100

 Hi,

emacs crashes with SIGABRT if i do following steps:

1. emacs -Q
2. M-: (setq-default bidi-display-reordering t)
3. M-x info
4. M->

unfortunately i can not provoke a backtrace with gdb, but i observe under gdb, that
after M-> and several C-p, the last `previous-line' fails in the "middle" of *info*
buffer with `Beginning of buffer' message.

Thanks.  I don't see any aborts, neither under GDB nor outside of it,
but I do see the "Beginning of buffer" messages.  I will look into
this.

Work-around: set Info-hide-note-references nil.  Could you please see
if this eliminates the crashes as well?

I can confirm, both problems are gone.

Another recipe to trigger the same bug:

  emacs -Q --eval "(setq-default bidi-display-reordering t)" etc\NEWS
-f vc-annotate

then type "v" (which runs vc-annotate-toggle-annotation-visibility)
and move around the "*Annotate NEWS (rev ...)*" buffer with up/down.

Right, thanks.

Should be fixed now on the trunk (revision 105208).
