Unhandled exception when reading from disconected socket

Question

I already do know, that it is impossible to simply detect if socket is disconnected or not - the server and clients must shout "Can you hear me?" and "Yeah I can." just like we do on skype.
But when boost::asio socket is disconnected from other side I obtain Unhanded exception when trying to read from socket. This is kind of disconnect detection useful enough for me. Can I handle that exception, so instead of crashing, the program will produce message in the console?
Some code for those who need it for everything:

bool SocketClient::read(int bytes, char *text) {
      char buffer = 0;
      int length = 0;
      while(bytes>0) {
        size_t len = sock.receive(boost::asio::buffer(&buffer, 1));  //boom: UNHANDLED EXCEPTION
        bytes--;
        text[length] = buffer;
        length++;

      }
      return true;
}

Because I am connecting to minecraft server, I know when the client is disconnected - exception is caused on any read/write attempt.

try
{
    size_t len = sock.receive(boost::asio::buffer(&buffer, 1));  //boom: UNHANDLED EXCEPTION
    // More code ...
}
catch (const boost::system::system_error& ex)
{
  if ( ex.code() == boost::asio::error::eof ) 
  {
    // Work your magic (console logging, retry , bailout etc.)
  }
}

Please also take a look at the doc. In the worst case , you could infer the exception type from the debugger :)
