The issue here is that the #defines EVFILT_READ and EVFILT_WRITE have the values -1 and -2. The original code translates that to filterRead = Filter -1 which is wrong Haskell and fails to compile. The modified code produces the correct code filterRead = Filter (-1) }}} -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7759#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
