Sorry, the minimal testcase should have been:

struct __attribute__ ((visibility("internal"))) A {};
struct B { A * a; }; /* warning: 'B' declared with greater visibility than the
type of its field 'B::a' [-Wattributes] */

struct C;
struct D { C * c; }; /* No warning */
struct __attribute__ ((visibility("internal"))) C {};
