It appears to diverge when running the following program | with 'runghc'. The main compiler can also be persuaded to diverge in | a similar fashion. Hugs exhibits correct behavior, ie, it prints | "hello". | | This is with GHC 6.4.2. I've tested on linux x86 and PPC OS X. | | | | newtype Mu a = Roll { unroll :: Mu a -> a } | | omega :: a | omega = (\x -> (unroll x) x) (Roll (\x -> (unroll x) x)) | | main = putStrLn "hello" | | | | Rob Dockins | | Speak softly and drive a Sherman tank. | Laugh hard; it's a long way to the bank. | -- TMBG | | | | _______________________________________________ | Glasgow-haskell-users mailing list | Glasgow-haskell-users@haskell.org | http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
