cl_UP is actually a pointer to a coefficient vector. This assignment creates
the pointer c which points to the same data as a. That's probably not what
you want. Perhaps you meant
c = a.ring()->create(degree(a));
for (std::size_t i = 0; i <= degree(a); ++i)

Wrong expectations from the user side.
Actually the semantics is a bit weird. Should we implement operator= which
"just works"? Or at least document the current behaviour?
All science is either physics or stamp collecting.
