Integer arithmetic gives the wrong answer on amd64/Linux
On x86 I get:
Prelude> reverse $ take 10 $ reverse $ show $ sum [ x ^ x | x <- [1..1000] ]
"9110846700"which is correct, but on amd64/Linux I get:
Prelude> reverse $ take 10 $ reverse $ show $ sum [ x ^ x | x <- [1..1000] ]
"0612504812"Both ghci's above are 6.4.1, but I also see it with the HEAD (a few days old).
Seen on Debian, Gentoo and rpath distributions.
Thanks Ian
