here's a complete program to reproduce the error:
module Main (main) where
main :: IO ()
main = withSocketsDo $ do
sock <- socket AF_INET Datagram 0
bindSocket sock $ SockAddrInet (PortNum 8888) iNADDR_ANY
recvFrom sock 65535
The output of netstat/TCPView after starting the program is:
MinSocketBind.exe:2724 UDP PC1:47138 *:*
By the way, I'm using GHC 6.10.4, which I think shouldn't make a difference.
