 The following program causes GHCi to crash, on x86 Linux and x86 Windows.

 {{{
 {-# LANGUAGE MagicHash #-}
 import System.Mem
 import GHC.Base

 main = do
   let list = concatMap buildThunk [0..10000]
   length list `seq` performGC
   print $ last list

 buildThunk :: Int -> [Int]
 buildThunk (I# k) = [f k]

 f :: Int# -> Int
 f x = I# x
 }}}
