Started failing with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=161655
Simplified testcase (only fails with cc1plus, not cc1):
typedef char A[20];
typedef A B[5];
struct C { B b; };

void
foo (void *x)
{
  char a[4 + sizeof (C)];
  C *c = (C *) (a + 4);
  for (int i = 0; i < 5; i++)
    __builtin___memcpy_chk (c->b[i], x, 20,
    __builtin_object_size (c->b[i], 0));
}
