Comment (by AntC):

 ?

 repeat of #14004 (or at least same code)

 To repeat Ryan's ticket:14004#comment:3 from there
 >> Your description still isn't very clear. What exactly is the bug here?

 Try:
 {{{
 instance {-# OVERLAPPING #-} (Eq a) => GEq a a where
      geq = (==)

 instance {-# OVERLAPPABLE #-} GEq a b where
      geq _ _ = False
 }}}
