Yes, thank you, that's same "internal logic" error as later.

One difference is that I think the above case cannot be
triggered by setMethod() .. one needs an explicit "artificial"
conformMethod() call.
Still, of course, it's wrong and should be corrected.
I've started to test changes .. maye not get to commit (with
enough confidence) before taking the train to
useR! 2019 @  Toulouse (France).
