Hi All,
can anybody explain me please why I get an access violation in the 
following code?
And why if I enable the std::cout in the stream_handler destructor the 
code work fine without exception?

I'm developing on windows XP, VS 2005.

Regards
Gianni

Here is the code:

#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/thread.hpp>
#include <boost/date_time/posix_time/posix_time_types.hpp>
#include <iostream>

typedef boost::shared_ptr<boost::asio::ip::tcp::socket> tcp_socket_ptr;

class stream_handler
{
public:

    stream_handler() :  acceptor(io_service)
    {
       boost::asio::ip::tcp::endpoint endpoint = 
boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), 22222);
       acceptor.open(endpoint.protocol());
       
acceptor.set_option(boost::asio::ip::tcp::acceptor::reuse_address(true));
       acceptor.bind(endpoint);
       acceptor.listen();

       socket = tcp_socket_ptr(new 
boost::asio::ip::tcp::socket(io_service));
       acceptor.async_accept(*socket, 
boost::bind(&stream_handler::handleAcceptForDebug, this, 
boost::asio::placeholders::error));

       work = boost::shared_ptr<boost::asio::io_service::work>(new 
boost::asio::io_service::work(io_service));
       thread = boost::thread(boost::bind(&boost::asio::io_service::run, 
&io_service));
    }

    virtual ~stream_handler()
    {
       //std::cout << __FUNCTION__ << std::endl;
       io_service.stop();
    }

private:

    boost::asio::io_service io_service;
    boost::shared_ptr<boost::asio::io_service::work> work;
    boost::asio::ip::tcp::acceptor acceptor;
    boost::thread thread;
    tcp_socket_ptr socket;

    void handleAcceptForDebug(const boost::system::error_code& iError) {};
};

int main(int argc, char** argv)
{
    stream_handler tcpsocket;
    return 0;
}
