Comment(by SimonHengel):

 The error on Windows is:

 {{{
 fd:4: hGetLine: end of file
 }}}

 The following test case works on Linux (an as far as I know on Mac OS X
 too), but not on Windows.
 {{{
 {-# OPTIONS_GHC -fno-warn-missing-signatures #-}
 module Spec (main) where
 import   Test.HUnit
 import   System.Process
 import   System.IO

 subprocess = concat $
   [ "module Main where\n"
   , "import System.IO\n"
   , "main = do\n"
   , "  hPutStr stderr \"foo\"\n"
   , "  hFlush stderr\n"
   , "  hPutStrLn stdout \"bar\"\n"
   , "  hFlush stdout\n"
   ]

 main = runTestTT $ TestCase $ do
   (Just hin, Just hout, Nothing, _) <-
 createProcess $ (proc "runhaskell" []) {
 std_in = CreatePipe
   , std_out = CreatePipe
   , std_err = UseHandle stdout
 }
   hPutStrLn hin subprocess
   hClose hin
   line <- hGetLine hout
   line @?= "foobar"
 }}}

 Do we consider this a bug?  If not, what would be the suggested way to do
 that?
