Subject: 23.0.91; Crashes on zooming pdf document
Date: Wed, 04 Mar 2009 21:17:30 +0300

To reproduce:

0) emacs -Q

1) Open a pdf document, for example this one:

   http://www.adobe.com/devnet/acrobat/pdfs/adobe_supplement_iso32000.pdf

2) Hit S-`+' several times. Emacs crashes once the width of the
   document page becomes wider than the window.

I'm ready to provide any additional info,
Andrey Paramonov

I can't reproduce this.  Could you run Emacs within GDB and get a
backtrace?  (You should make sure that Emacs is compiled with debugging
symbols, and ideally with no optimizations; `CFLAGS="-g" ./configure'
will do that.)

Unfortunately, the interesting parts of the backtrace are optimized out.
Could you try to compile without optimizations and get a backtrace with
the non-optimized Emacs, preferably using the CVS version?  (To compile
without optimizations, do: CFLAGS="-g" ./configure)

Also, what is your LANG environment variable?

My LANG is ru_RU.UTF-8; the more detailed information can be found in
the starting post. I've just tried to reproduce the bug in C locale,
and it is not reproducible. The problem seems to be indeed connected
with the internationalization.

Could you please try to reproduce the bug in ru_RU.UTF-8 locale? If it
is problematic, I'll try to find time to undertake the Emacs
compilation. I use Debian GNU\Linux, so I have never compiled Emacs
from source before. The thing I'm afraid of is that my compilation
would interfere with the APT system the bad way.

I can't reproduce this with LANG=ru_RU.UTF-8.  Could you try to compile?
It won't interfere with the APT system if you don't do `make install'
after compilation; just run the binary directly from the compilation
directory (emacs/src/emacs).

Thanks.  Please show the output of the following debugger commands:

f 15
p reason
xtype
xstring

(You need gdb to be running the Emacs src directory for the xtype and
xstring gdb commands to work).

Hello!

Any progress on this bug? I can still reproduce it on the latest Emacs
snapshot.

I think this bug is now fixed.  Could you try again with latest Emacs
CVS?
