hexl-mode: spurious characters


From: Alan Donovan
Subject: hexl-mode: spurious characters
Date: Tue, 19 Mar 2002 01:55:28 -0500

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.1 (i386-redhat-linux-gnu, X toolkit)
 of Fri Mar 16 2001 on porky.devel.redhat.com
configured using `configure  --mandir=/usr/share/man
--infodir=/usr/share/info --prefix=/usr --libexecdir=/usr/lib
--sharedstatedir=/var --with-gcc --with-pop --with-x-toolkit
i386-redhat-linux-gnu'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Entering hexl-mode from an existing unmodified buffer gives different
results than if one loads that file with hexl-find-file.  This is
easily reproducible:

sh% head --bytes=10 /dev/random >rand1
sh% cp rand1 rand2

C-x C-f rand
M-x hexl-mode
C-x 2
M-x hexl-find-file rand2

You can see that the first buffer contains several spurious 0x81
characters. I have no idea what it is, but it is extremely confusing
and it took me a while before I suspected Emacs was to blame

Please let me know if I can help further.

cheers
alan
