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.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

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

22 Apr 2005

create a file with the following octal dump (i.e., od -c file) in emacs 21.3.1:

0000000   h   e   l   l   o 033   4 033   S 001   h   e   l   l   o  \n
0000020

These contents are "hello(esc)4(esc)S(ctrl-A)hello\n".  I type them here
in representational form rather than the exact form to avoid the potential 
problem of your emacs version crashing on reading this bug message and being
unable to decipher it.

When I read this very simple file with emacs version 21.3.1, the message
Fatal error (6).Aborted
appears and the emacs process aborts.  It will not read this file.  Interestingly,
emacs 21.3.1 will create this file and write it out.  Upon deleting the corresponding
buffer and re-reading the file, it crashes.  This happens every time.

Version 20.4.1 of emacs does not exhibit this problem.  It creates the test file,
writes it out, and re-reads it with no difficulty after deleting the corresponding
buffer.  Some problem has been introduced in the newer version leading to this
crash phenomenon.
