shared_ptr智能指针作为参数的问题

[john_liqinghan]

class connection{
    ....
};

class iodriver{
public:
       void start_accept();
       void handle_accept(connection pConnect, const boost::system::error_code& error);
private:
       boost::asio::io_service        m_IOServer;     //IO句柄
       boost::asio::ip::tcp::acceptor m_acceptor;     //套接字接收器
}
typedef boost::shared_ptr<connection> connection_ptr;

void iodriver:start_accept()
{
	connection_ptr pConnect = connection_ptr(new connection(m_IOServer));
	m_acceptor.async_accept(pConnect ->GetSock(), boost::bind(&iodirver::handle_accept, this, pConnect , boost::asio::placeholders::error));
}

void odriver::handle_accept(connection_ptr pConnect, const boost::system::error_code& error)
{
	if (!error)
	{
		boost::system::error_code err;
		unsigned int uPort = pConnect->GetSock().remote_endpoint(err).port();
		std::string strIp = pConnect->GetSock().remote_endpoint(err).address().to_string();
		printf("+accept socket form [%s-%u][0x%x]", strIp.c_str(), uPort, pConnect.get());
		m_xNewConnect.AddConnect(pConnect);
		start_recv_head(pConnect);
	}
	else
	{
		printf("accept error [%d]", error.value());
	}
	start_accept();
}

void iodriver::start_recv_head(connection_ptr pConnect)
{
	xWMessage_ptr pMsg = xWMessage_ptr(new xWMessage);
	boost::asio::async_read(pConnect->GetSock(), boost::asio::buffer(pMsg->head_data(), xWMessage::Msg_Head_Len), boost::bind(&xIODirve::handle_recv_head, this, pConnect, pMsg, _1));
}

void iodriver::handle_recv_head(connection_ptr pConnect, xWMessage_ptr pMsg, const boost::system::error_code& error)
{
	if (!error)
	{
	   start_recv_head(pConnect);
		
	}
	else
	{
		printf("recv one msg head error[%u] \n", error.value());
                //偶尔存在此处会打印995错误
                ....
	}
}

handle_recv_head函数会打印995错误，因为对智能指针不了解，不知道这个问题怎么引起的。请大家帮帮忙。该如何改正这个错误。

哪里能看出是智能指针导致的？？

[john_liqinghan]

我知道原因了，不是这个问题引起的
