[ENet-discuss] ENetPeer->data and enet_host_service

[Ruud van Gaal]

Try printing the pointer values as you assign/new (on connect) and
free/delete (on disconnect). Then print pointer where you access your local
'peer' pointers.
You'll probably find that you access a peer after it has been deleted or
such, my guess.
