Comment(by igloo):

 Daniel, what platform are you on?

 It looks right here:
 {{{
 $ '/home/ian/ghc/7.0-branch/ghc/inplace/bin/ghc-stage2' -fforce-recomp
 -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-conf -rtsopts
 -o T4321 T4321.hs  -O
 $ ./T4321
 3.1415926535897643
 $ cat T4321.stdout
 3.1415926535897643
 }}}
 (and similarly passes all ways), and is run the "normal" way as part of
 validate, so I imagine works on the other common platforms too.
