That's undefined.  This isn't undefined:

    static inline void increment (int * ptr) { *ptr++; return 0; }
    func (increment (&a), increment (&a));

I'm not sure where this is defined or not, or whether it should be:

    #define increment(ptr) ({ *(ptr)++; 0; })
    func (increment (&a), increment (&a));
