[Haskell-cafe] Data.Ranges show error

[Aaron Gray]

I am getting the following error when trying to do a show on a Ranges object
:-

C:\Languages\Haskell>ghci rangeTest.hs
GHCi, version 6.12.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
[1 of 1] Compiling Main             ( rangeTest.hs, interpreted )
Ok, modules loaded: Main.
*Main> main

Loading package ranges-0.2.3 ... linking ... done.
Ranges [(37*** Exception: <stdout>: hPutChar: invalid argument (character is
not
 in the code page)
*Main>

I have attached the test source also :-

    import Data.Ranges

    test = (ranges [
        range 32 33,
        range 34 35,
        range 37 39
        ])


    main :: IO ()
    main = do {
        putStrLn (show test)
        }

I am probably doing something fundermentaly wrong.

Many thanks in advance,

Aaron
