4911	GHC 7 does not process Handle correctly	kazu-yamamoto		"Compile the following code:

{{{
module Main where

import qualified Data.ByteString.Lazy.Char8 as L

main :: IO ()
main = do
    getLine >>= putStrLn
    L.getContents >>= L.putStr
}}}

Let's call this binary ""foo"". If you compile this with GHC 6.12.3, the following command work well. That is, the entire of ""any-file"" is displayed.

{{{
% foo < any-file
}}}

However, if you compile this with GHC 7.0.1 or later, the command displays only the first line of ""any-file"".

This can be re-produced on Linux.
