Deriving Bug?
ghci -XDeriveDataTypeable
> import Data.Typeable
> data S = S deriving (typeable)
ghc: panic! (the 'impossible' happened)
(GHC version 7.4.2 for x86_64-unknown-linux):
nameModule typeable{tv av8}
Please report ...
data S = S deriving typeable causes a parse error and The following work just fine:
data S = S deriving Typeable
data S = S deriving (Typeable)
data S = S deriving (show) causes a similar error the only change being:
nameModule show{tv av8}
The same problem exists outside of ghci when trying to compile with GHC.
The ascii tree for the dependancies of the ghc install produced with
