Comment (by SimonKing):
Note that I did experience a very subtle Cython problem: When one
constructs a Python class that simultaneously inherits from `RingElement`
and `Morphism`, then the two bases seem to have a compatible layout,
however two ''different'' cpdef attributes of the two bases get confused.
Perhaps this is similar here?
Sorry, I am too lazy to look up the ticket number or the discussion on the
cython-user mailing list.
