--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Testcase which is miscompiled since r15-7810:
struct R
{
  int a, b;
  constexpr R () : a (0), b (1) { }
  constexpr R (int x, int y) : a (x), b (y) {}
};

R *
foo (int *p)
{
  return new R[64] { R (++*p, 43) };
}

int
main ()
{
  int x = 41;
  R *p = foo (&x);
  if (x != 42 || p[0].a != 42 || p[0].b != 43)
    __builtin_abort ();
  for (int i = 1; i < 64; ++i)
    if (p[i].a != 0 || p[i].b != 1)
      __builtin_abort ();
}
