I should have been more specific... the bug doesn't manifest itself when
I compile a Haskell file directly, but does if I compile it to Core and
then compile the .hcr file. For example:
$ ghc -fext-core -fno-code hello.hs
$ ghc hello.hcr

where hello.hs is:
main = putStr $ "Hello world!" ++ (show (foo 2)) ++ (show (foo 0))
data Bar = Foo String | Baz Int
deriving Show
foo x = if (x == 0) then
Foo "zero"
else
Baz x
