Import GHC.Err so we see bottoming functions properly Before this patch, GHC/Err.lhs-boot exported divZeroError and overflowError, as well as plain 'error'. The latter has a wired-in defn in GHC (MkId.lhs), but the former two do not. As a result GHC doesn't see that overflowError is a bottoming function at a crucial moment when compiling GHC.Real, and that means that divMod wasn't getting the CPR property. The fix is easy: - GHC/Err.lhs-boot should export only 'error' - GHC.Real, GHC.Int, and GHC.Word should import GHC.Err directly. They can do this nowadays without creating a module loop, thanks to the new exception story
