Comment (by simonpj):

 Well this ticket was about a bug in GHC that meant it really didn't
 compile *at all*.  Now, from what you say, it does.  But there may still
 be a problem with the amount of code that `deriving Binary` generates
 (hence copying Pedro), perhaps due to nested tuples (which might be helped
 by the new SOP approach) or perhaps due to over-enthusiastic INLINE
 pragmas.

 In any case, I don't think there's a bug in GHC any more.  But I'll leave
 this ticket open in the hope that we may make progress on the `deriving
 Binary` question.

 Simon
