Comment(by spancratz):
Apart from a bad indentation in ``polynomial_quotient_ring_element``, for
which I didn't want to re-upload a patch, I am now down to the following
doctest failures:
{{{
sage -t
"devel/sage/sage/schemes/elliptic_curves/padic_lseries.py"
sage -t "devel/sage/sage/schemes/elliptic_curves/ell_generic.py"
sage -t "devel/sage/sage/schemes/elliptic_curves/padics.py"
sage -t
"devel/sage/sage/schemes/elliptic_curves/ell_curve_isogeny.py"
sage -t "devel/sage/sage/tests/book_stein_modform.py"
sage -t "devel/sage/sage/rings/qqbar.py"
sage -t
"devel/sage/sage/rings/number_field/number_field_element.pyx"
sage -t "devel/sage/sage/modular/modform/element.py"
sage -t "devel/sage/sage/modular/overconvergent/genus0.py"
sage -t "devel/sage/sage/modular/hecke/submodule.py"
sage -t "devel/sage/sage/structure/sage_object.pyx"
}}}
All but one of them are memory problems, either in ``mpq_canonicalize``
(called in the ``__getitem__`` method) or in ``fmpz_poly_mul`` called in
``celement_mul``. At the moment, I do not know how to resolve these.
