--- Comment #2 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
No, it *is* initializing a pointer.  You cannot initialize a struct with 0. 
Instead the initializer is considered "flattened" in C.

For example:

struct s2 {
        int  *x;
        int y;
};

int t;

int
main(void)
{
        struct s2  a2[] = {0, 1, &t, 2};
        _Static_assert(sizeof(a2) == sizeof(struct s2) * 2);
}
