Re: Crash when trying to use utf-8

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! I've tried to follow Stephen Turnbull's instructions at http://turnbull.sk.tsukuba.ac.jp/Tools/XEmacs/XEmacs+Unicode.html for using UTF-8. I'm using 21.4.8 built with mule, and I used the following code (executed manually from a scratch buffer after startup): (require 'un-define) (require 'unicode) (set-coding-category-system 'utf-8 'utf-8) (set-coding-priority-list '(utf-8)) I then executed file-find to load a sample UTF-8 file, and XEmacs bombed out. Running gdb on the core dump gives: Program terminated with signal 11, Segmentation fault.

I'm guessing that even if I'm doing something wrong there is also a problem here, as XEmacs shouldn't bomb out like this? Or I'm doing something seriously wrong... I can view the file fine in xterm. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux mnemosyne 2.4.18-4 #1 Thu May 2 18:10:25 EDT 2002 i686 unknown ./configure '--prefix=/home/rrt' '--with-mule' XEmacs 21.4.8 "Honest Recruiter" configured for `i686-pc-linux'.
