Solved. The error is inside bind I used a boost::ref to the shared_pointer, so the shared_pointer didn't get incremented, it was destroyed. 2009/12/15 Germán Diago <germandiago@gmail.com>:

Hello. I have this code (the variables that end with _ are instance variables). The code works well as is, in a synchronous way.

void tcpServer::startAccept() {        tcpConnection::pointer new_connection =        tcpConnection::create(acceptor_.io_service());        boost::system::error_code error;

       acceptor_.accept(new_connection->socket());        onAccept(new_connection, boost::system::error_code()); }

void tcpServer::onAccept(tcpConnection::pointer new_connection,                 const boost::system::error_code & error) {        if (!error)        {                if (currentconnections_ < maxconnections_)                {                        boost::lock_guard<boost::mutex> l(mutexcurrconnections_);

                       /*connectionsinfo_.push_back(ServerConnectionInfoPtr(new ServerConnectionInfo(                                new_connection->socket().remote_endpoint().address().to_string(),                                new_connection->socket().remote_endpoint().port(),                                new_connection)));                        */                        currentconnections_++;

               }                else throw std::runtime_error("The server is full. No more connections accepted");

               /*boost::asio::async_read(new_connection->socket(), boost::asio::buffer(bufferread_),                                boost::bind(&tcpServer::onRead, this, _1, _2));                */                vector<char> vecrecv(12);                std::size_t readsize = boost::asio::read(new_connection->socket(), boost::asio::buffer(vecrecv));                cout << "Server received " << readsize << " bytes: " << endl;                copy(vecrecv.begin(), vecrecv.end(), ostream_iterator<char>(cout));                cout << endl;

               std::string helloclient = "hello client";                std::vector<char> sendvec(helloclient.begin(), helloclient.end());

               //TODO:Cambiar por receiveAllData()

               //std::size_t writesize = new_connection->socket().send(boost::asio::buffer(sendvec, sendvec.size()));                std::size_t writesize = boost::asio::write(new_connection->socket(), boost::asio::buffer(sendvec));                std::cout << "Written " << writesize << " bytes" << std::endl;        }        startAccept(); }

But if I change the function startAccept so that instead of doing what it used to do, it does an asynchronous_accept:

void tcpServer::startAccept() {        tcpConnection::pointer new_connection =        tcpConnection::create(acceptor_.io_service());        boost::system::error_code error;

       acceptor_.async_accept(new_connection->socket(),        boost::bind(&tcpServer::onAccept, this, boost::ref(new_connection),                        boost::asio::placeholders::error)); }

I get the following errors:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error>

...

'  what():  Socket operation on non-socket terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> '  what():  Connection reset by peer

Anyone can help? I have no clue of what's happening. The socket is a shared_ptr, so it should be there when I use onAccept. Don't know what happens. Thanks for your time.
