下面这段代码有一个非常麻烦的内存泄漏，即使使用 Valgrind，我也无法查明。

void connect_handler(const boost::system::error_code& error)
{
  if (!error)
    std::cout << "Connected to server successfully." << std::endl;
}

void read_handler(const boost::system::error_code& error, 
                  std::size_t bytes_transferred)
{
  if (!error) {
    std::cout << "Transferred " << bytes_transferred 
              << "bytes." << std::endl;
  }
}

int main(int argc, char* argv[])
{
  try
  {
    if (argc != 3)
    {
      std::cerr << "Usage: client <host> <port>" << std::endl;
      return 1;
    }

    boost::asio::io_service io_service;

    boost::asio::ip::tcp::resolver resolver(io_service);
    boost::asio::ip::tcp::resolver::query query(argv[1], argv[2],
      boost::asio::ip::resolver_query_base::numeric_service);
    boost::asio::ip::tcp::resolver::iterator endpoint_iterator = 
      resolver.resolve(query);

    boost::asio::ip::tcp::socket socket(io_service);
    boost::asio::async_connect(socket, endpoint_iterator, …
