Perhaps you already know this problem, but I want to flag it for
completeness.
When I add
(setq-default bidi-display-reordering t)
to my ~/.emacs file causes Emacs (current trunk) to hang when I try to
visit a PDF or JPG file (docview-mode).
This happens both on Cygwin and GNU/Linux Kubuntu 10.04.
Ciao, ciao,
Angelo.

No, I didn't.

Please show a full recipe, starting with "emacs -Q". Thanks.

The simplest way I found (but I am sure there is another more simpler) is:
emacs -Q &
then in scratch buffer evaluate (C-M-x):
(setq-default bidi-display-reordering t)
Then C-x C-f pdf_or_jpg_file
Here Emacs hangs ('top' shows 100% CPU!)
Hope this is useful...
Ciao,
Angelo.

I just tried this recipe on GNU Emacs 24.0.50.2 (i686-pc-linux-gnu, GTK+
Version 2.18.6) of 2010-05-08 on escher with a JPG file and Emacs dumped
core. The gdb backtrace from the core file is attached.

Could you please post that JPG file as an attachment? I don't see a
crash, only an infloop, so perhaps there's more than one problem, or
maybe the bug is data-dependent.
I know what the problem is, at least what's responsible for the
infloop, and will fix it soon in the repository. But please post the
file that crashes nonetheless, so I could make sure there are no
further problems.
Thanks.

I think you're right that the crash is data-dependent: I tried the
recipe on several other JPG and PDF files, and they all made Emacs
infloop but not abort. I then experimented with the file that induced
the crash (of which file(1) says: JPEG image data, EXIF standard 2.21):
- First I found that the crash still happens when Emacs tries to visit a
file consisting of only a fairly small initial segment of the original
JPG file.
- Then I tried even smaller initial segments, but they all only made
Emacs infloop, not crash.
- Then I tried a non-initial segment, starting from the end position of
the largest initial segment that induced the infloop but not the crash,
and ending with the end of the segment that induced the crash, and
voila! -- Emacs crashed. The backtrace I got from the core file was
essentially the same as the one I posted to the list, modulo values of
variables.
- Then I renamed this file (the non-initial segment that induced a
crash) from "test8.jpg" to simply "test", ran the recipe -- and Emacs
successfully visited the file, no crash, no hang.
So I've attached this file, which again, is a small non-initial segment
of a JPG file (and as such not recognized by file(1) as a JPG file);
(only) if its name ends in .jpg and (setq-default
bidi-display-reordering t) is evaluated, Emacs crashes upon visiting
this file. I hope it helps you shed some light on the problem.
