Comment:
I poked around a little to see if I could make a smaller deterministic
test case and came up with this:
{{{
#!hs
main = print $ encodeFloat 2 6
}}}
Resulting in:
{{{
PS C:\hg\haskell\trac\4914> ghc --make bug.hs .\hook.o -fforce-recomp
[1 of 1] Compiling Main ( bug.hs, bug.o )
Linking bug.exe ...
PS C:\hg\haskell\trac\4914> .\bug.exe
128.0
OnExitHook: NONEMPTY FPU Stack (7)
}}}
