Stack overflow when optimizing recursive newtype
I have
module Bug where
newtype Void = Void Void
data Decision a = Disproved (a -> Void)
foo :: () -> Decision Int
foo _ = Disproved (\_ -> undefined)When I
> ghc -O Bug.hsI get
[1 of 1] Compiling Bug ( Bug.hs, Bug.o )
stack overflow: use +RTS -K<size> to increase itThe module compiles fine without -O. This was tested on 7.7.20131011.
