关于BOOST引用问题

#include "stdafx.h"

#include <stdio.h>

#include <boost/asio.hpp>

#include <boost/bind.hpp>

#include<boost/date_time/posix_time/posix_time.hpp>

using namespace boost;

void print(const asio::error&/*e*/,asio::deadline_timer *t,int* count)

{

    if (*count <5)

    {

        std::cout<<*count<<"\n";

        ++(*count);



        t->expires_at(t->expires_at()+boost::posix_time::seconds(1));

        t->async_wait(boost::bind(print,asio::placeholders::error,t,count));

    }

}

int _tmain(int argc, _TCHAR* argv[])

{

    asio::io_service io;

    int count =0;

    asio::deadline_timer t(io,boost::posix_time::seconds(1));

    t.async_wait(boost::bind(print,asio::placeholders::error,&t,&count));



    io.run();



    std::cout<<"Final count is"<<count<<"\n";



    return 0;

}

会出现下面的错：

请问这是怎么回事啊？
