2) At least ghc-7.8.3 and ghc-7.10.1 do the same in this example.
May be, you can change this example a bit to make ghc-7.8.3 and
ghc-7.10.1 diverse, so that my example bug becomes visible?

I finally found time to look into what is happening here. It’s a good

instance (...)= Ring (ResidueE a) (A)
instance (..., Ring
Now, I delete `OverlappingInstances' from docon.cabal
and also from the $doconCpOpt options to call ghc on
demotest/Main.hs.
And now the test runs correct in ghc-7.10.1 !
Only it is 1.5 times slower than in ghc-7.8.2.
So:
a) The test intends overlapping instances,
b) instance
