Not sure if it's related to your problem, but AFAICT you are not 
managing your resources in a correct way. Everything passed to an 
'async_' function should outlive the full async operation. E.g., in your 
'send' function you use a RValue string -- this will most probably not 
outlive the async_send_to operation.

Perhaps related to your problem, is that you are counting the number of 
"received_from" callbacks, not the number of received messages. Couldn't 
it be that you receive multiple messages in one callback?
