[Haskell-cafe] hPutStrLn and hFlush

[Gracjan Polak]

Hi all,

A bit strange behaviour with hPutStrLn. Consider following program:

main = do
    handle <- openFile "output.txt" WriteMode
    hPutStrLn handle (unlines contLines2)
    -- hFlush houtput
    where
        contLines2 = flip map [1..2000] $
              \x -> show x ++ " been there done that"

Outputs file which ends with following lines:

1989 been there done that
1990 been there done that
1991 been there done that
1992 been there done that
199
(END)

So the output is truncated. When I uncomment hFlush, file is fully written.
Is this expected/documented behaviour?

Platform: WinXP, GHC version 6.4.1
