Comment(by singpolyma):

 The following code *works*, so the integer can exist and operations can be
 done on it, but certain operations apparently cause it to fail:

 {{{
 module Main(main) where

 import Data.Char

 newShow' :: Integer -> [Int]
 newShow' 0 = []
 newShow' x = (fromIntegral $ x `mod` 10) : newShow' (x `div` 10)

 newShow :: Integer -> String
 newShow x = map intToDigit $ reverse (newShow' x)

 main :: IO ()
 main = print $ newShow x
         where
         x =
