Floating point error with -msse2

Compile and run this program:

main = print (cos 0)

And you get

$ ghc -O2 -fforce-recomp -msse2 Main.hs
[1 of 1] Compiling Main             ( Main.hs, Main.o )
Linking Main.exe ...
$ ./Main
5.249681779125557e-308

(This is a bug in ghc 7.2.2, but that 7.2.2 is not one of the available version choices.)
