--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note this works on the trunk:
```
struct Base
{
  constexpr virtual ~Base() {}
//  constexpr Base* get_this() { return this; }
  int x;
};

struct Derived : public Base {};

constexpr bool test()
{
  Derived* pf = new Derived;
  Base* t = pf;
  delete t;
  return true;
}

constexpr bool b = test();
```
