On #haskell we recently had a discussion about the following:<br>
<br>
import System.Random<br>
<br>
list <- replicateM 1000000 randomIO :: IO [Int]<br>
<br>
I would think that this gives us a list of a million random Ints. In<br>
fact, this is what happens in ghci. But with ghc we get:<br>
<br>
Stack space overflow: current size 8388608 bytes.<br>
Use `+RTS -Ksize -RTS' to increase it.<br>
