   Summary: std::shared_ptr requires public destructor for a class
with friend deleter
   Product: gcc

AssignedTo: unassig...@gcc.gnu.org

Code example and compiler output

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

The boost shared_ptr works OK.
