I've lost track of this thread, but if you still think there's a bug
then can you report it in the GHC trac please?:
http://hackage.haskell.org/trac/ghc/wiki/ReportABug

Please give an example without UndecidableInstances if possible, and the
smaller the example is the easier it is for us to look into it.

Thanks
Ian
