Hi, I am a newcomer to ghc-devs mailing list and I volunteer to fix this issue.

Wonderful!

Since base-4.10.0.0, the `IntPtr` and `WordPtr` are defined using `newtype` rather than `data` (as in base-4.9.1.0), is it enough for this issue that putting the following instance declarations to `Data.Data` module (with `GeneralizedNewtypeDeriving` enabled) ?

{{{#!haskell deriving instance Data IntPtr

deriving instance Data WordPtr }}}

Yes, I think that would work quite nicely. Feel free to ask any more questions here if they arise. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13115#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
