No such example exists, at least not in portable code.  N1570
6.10.3.2p1:

    Constraints

    Each # preprocessing token in the replacement list for a
    function-like macro shall be followed by a parameter as the
    next preprocessing token in the wreplacement list.

(C90 has similar wording.)
