run time crash encountered

run time crash encountered

[-- Attachment #1: Type: text/plain, Size: 4046 bytes --]


Background: 
  emacs version: GNU Emacs 23.0.60.1 (i686-pc-cygwin, X toolkit) of 2008-06-26
  O.S.: CYGWIN_NT-5.1 1.5.25 (posix compliant)
  X-11: Window system


The built and installed new emacs (as of June/25/2008) crashes, when I attempt to read in a file containing "iso-2022-jp" encoded characters.  ISO-8859-1 was no problem.  I happens with the Japanese iso-2022-jp encoded files.  The system crashes and dump
s unceremoniouly.  I'd like to find out why and fix it.

Attached is a example file that causes a stack dump, when a vist to it is attempted.

Beloe is the backtrace of the system prior to crashing

I'd appreciate and aid or advice in solving this.

Truely, 
  Darel Henman

FWIW, I don't get a crash visiting the file, and it displays correctly.

From the stack backtrace, it seems to be a problem with fontconfig
(though I'm using debian and you're using windows, which undoubtedly
affects things).

I've just installed a fix.  But, as I have not tested `ftx'
font-driver for a long time, please watch out.

BTW, I didn't know that ftx driver is usable on Windows.

Kenichi, 
   the fix you installed is successfull.  Thank you, I appreciate it.

  "cygwin" provides a port of the X Window System, called cygwin/X.  It Cygwin/X provides an X Server, X libraries, and nearly all of the standard X clients.  This enables easier porting of software.  cygwin has the fontconfig library which ftfont.c call
s.
  A good practical example, of cygwin is to put it and your favority tools and applications installed on a usb memory stick, One can then sit down at any Windows machine and virtually defenestrate it, as least temporarily, by using one's own cygwin envir
onment dll, X11, emacs, shells, and other tools, and maybe a game of go..

Regards,
   Darel Henman

Doesn't xft not supported in cygwin?  Or you just don't
install it?  If configure finds Xft, Emacs should use xft
backend instead of ftx backend.
