[Bug c++/20763] [4.0 regression] Incompatible struct alignment change

typedef void *voidp;

struct S
{
  char a;
  voidp __attribute__ ((aligned (16))) b;
};

struct T
{
  char a;
  void *__attribute__ ((aligned (16))) b;
};

int f[sizeof (struct S) != sizeof (struct T) ? -1 : 1];

also fails, on all arches I tried (16 byte alignment so that it fails also
on 64-bit arches).
