What the standard does guarantee is that a pointer to a struct can be
cast to a pointer to its first member and vice versa.  It does not as
far as I can see guarantee that a pointer to something of the same type
of its first member can be converted to a pointer to a struct even if
the struct only contains a member of such type.
