Emacs always gave me the following message when I tried to simulate 
the function "tr - translate characters".

	       Error message from emacs:

	Fatal error (4).Illegal instruction (core dumped)

The steps I did were:
  1. echo "abcd" > test         #generate a test file
  2. /usr/local/emacs -q test 	#invoke emacs without loading my init file.
  3. In emacs, do the following command:

       M-x replace-regexp RET \(a\)\|\(b\) RET \1Z\2Y RET

	(Trying to translate "a" to "Z" and "b" to "Y".
	This can be done by "tr ab ZY".
	Actually, I was trying to translate control characters
	to normal characters, for example, from \C-x to x.)	
	
  4. A fatal error was issued by emacs.  Emacs died after that message.

Is this an emacs bug?
