All versions ran without printing errors.
I seem to recall that GHC produces sse2 code on x86_64. If that's correct, the effect probably won't be reproducible on that architecture, since it doesn't occur with -msse2 on x86 either (well, at least on my machine).
This is GHC 7.0.3 on Windows XP 32-bit: $ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.0.3 $ ls cabal-dev bin cabal.config doc logs packages packages-7.0.3.conf primitive-0.3.1 vector-0.7.0.1 vector-algorithms-0.4 $ ./cabal-dev/bin/test.exe After sorting: 674 NaNs.
