Actually, there's no need here to delete through the base pointer; so this is
perhaps simpler:

struct Base
{
  constexpr Base* get_this() { return this; }
  int x;
};

struct Derived : public Base {};

constexpr bool test()
{
  Derived* pf = new Derived;

  delete static_cast<Derived*>(pf->get_this());

  return true;
}

constexpr bool b = test();
