I am having a timeout example code problem, modified code is below:
class connect_handler
{
public:
   connect_handler(io_service& ios)
     : io_service_(ios),
       timer_(ios),
       socket_(ios)
   {
     socket_.async_connect(
         tcp::endpoint(boost::asio::ip::address_v4::loopback(), 32123),
         boost::bind(&connect_handler::handle_connect, this,
           boost::asio::placeholders::error));

     timer_.expires_from_now(boost::posix_time::seconds(5));
     timer_.async_wait(boost::bind(&connect_handler::close, this));
   }

   void handle_connect(const boost::system::error_code& err)
   {
     if (err)
     {
       std::cout << "Connect error: " << err.message() << "\n";
     }
     e
lse
     {
      // We need to cancel the timeout since we have connected.
      timer_.cancel(); // < Fires the timer regardless. Because we are  
calling cancel() from inside an io_service call???
       std::cout << "Successful connection\n";
     }
   }

   void close()
   {
     socket_.close();
   }

private:
   io_service& io_service_;
   deadline_timer timer_;
   tcp::socket socket_;
};
