[Haskell-cafe] enumFrom* strangeness on GHC?

[Felipe Almeida Lessa]

Hello =),

I'm puzzled, and maybe someone can help me out. Why does this happens?

$ time ghci -e "last $ take 1000000 $ [1..1000000]"
1000000

real    0m0.673s
user    0m0.554s
sys     0m0.024s

$ time ghci -e "last $ take 1000000 $ [1..]"
*** Exception: stack overflow

real    0m1.305s
user    0m1.057s
sys     0m0.062s

$ ghci -V
The Glorious Glasgow Haskell Compilation System, version 6.6


Looking at http://darcs.haskell.org/ghc-6.6/packages/base/GHC/Enum.lhs
, I still have no clue of what may be happening. Any ideas? Should I
file a bug on GHC?

Thanks,
