It prints n, rather than tak(3n,2n,n).

The same with some versions of ghc.

Ah .. it seems to be a bug in gcc 4.0

The Glorious Glasgow Haskell Compilation System, version 6.4 [running on Ubuntu which uses Debian package]

gcc (GCC) 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9) x86_64

Summary: gcc does not work with GHC 6.4 on x86_64 with optimisation higher than -O1

Perhaps the Evil Mangler is not working, or, possibly the version isn't even registered.

Thanks for the report, I'll look into gcc 4.x before we release 6.4.2. Cheers, Simon
