--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r14-5503-gd3f48f682271ed94ab6e9f6bc62418a62bd8ff26
Slightly shortened testcase which aborts on error:
struct A { void *a; };
struct B { void *b; };
struct C : public B, public A { A c; };
static C d;

int
main ()
{
  auto C::*e = &C::c;
  auto f = &(d.*e);
  auto g = &d.c;
  if (f != g)
    __builtin_abort ();
}
