Apple clang rejects taking the address of a flexible array member that carries a counted_by attribute. A future patch wants to add that attribute to two such places. To avoid problems, use the array itself instead taking its address with &, which yields the same address. (There are a few more, but they are not candidates for a counted_by attribute, so they are left alone here.)
