Hello,

Maybe this is a bug?

I've been experimenting with the Socket library supplied
with ghc version 4.08.1. I'm using "awajicho", a SPARC 
station running Solaris 2.7. Now when I compile these two 
modules:

module Main where 	----------  module X -----------

import Socket
import Posix

main :: IO () 
main = 
   do { sendTo "awajicho" (PortNumber (mkPortNumber 5000)) "abcd1234"
      ; s <- recvFrom "awajicho" (PortNumber (mkPortNumber 5001))
      ; putStrLn s
      }

module Main where	----------- module Y ----------------

import Socket
import Posix

main :: IO () 
main = 
   do { s <- recvFrom "awajicho" (PortNumber (mkPortNumber 5000))
      ; sendTo "awajicho" (PortNumber (mkPortNumber 5001)) s 
      }

like this:

$ ghc X.hs -o x -syslib posix -syslib net
$ ghc Y.hs -o y -syslib posix -syslib net

and run the code:

$ ./y &
12935
$ x
1234abcd

$ ./y &
12938
$ x
1234bacd

All of which is (to me at least) rather strange. I would expect abcd1234.

Any idea what I'm doing wrong?

Responses to D.Wakeling at ex.ac.uk and the list please,

Thanks
