Further discussion on comp.std.c turned up C99 6.5.2.2p5, which says in part:

    If an attempt is made to modify the result of a function call or to
    access it after the next sequence point, the behavior is undefined.

So the value of ptr cannot be used after its initialization without
invoking undefined behavior.  I suggest that this should result in  
a warning.
