Hi,

can confirm this bug.
GNU Emacs 23.2.94.1 (i686-pc-linux-gnu, GTK+ Version 2.18.6) of 2011-02-25

Error is in backward-prefix-chars, ie. in syntax.c AFAIS.

line 2855

   while (!char_quoted (pos, pos_byte)
	 /* Previous statement updates syntax table.  */
	 && ((c = FETCH_CHAR_AS_MULTIBYTE (pos_byte), SYNTAX (c) == Squote)
	     || SYNTAX_PREFIX (c)))
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

may that `or' SYNTAX_PREFIX above?
