Code example and compiler output

class TestA
{
public:
  static std::shared_ptr<TestA> CreateTestA();

private:
  TestA();
  ~TestA();

private:
  class Deleter;
  friend class Deleter;

};

class TestA::Deleter
{
public:
  void operator()( TestA * p)
  {
    std::cout << "Deleting TestA\n";
    delete p;
  }
};

std::shared_ptr<TestA> TestA::CreateTestA()
{
  return std::shared_ptr<TestA>(
                                new TestA(),
                                TestA::Deleter()
                                );
}
will not compile:
error: ‘TestA::~TestA()’ is private

The boost shared_ptr works OK.
