Comment(by SimonKing):
I have attached my experimental rebasement (relative to #7797 on top of
sage-4.7.2.alpha3), but not all is good.
There are quite a lot of doctest failures, including some very wrong
arithmetical results in plural.pyx.
Less dramatic: There are some zero division errors (for example in
doctests of mul
ti_polynomial_libsingular.pyx) where the expected error message was
"rational division by zero", but now there is ''no'' error message (but
there is a `ZeroDivisionError`, at least).
There is a segment fault in the tests of multi_polynomial_ideal.py. I
guess it is the same segfault that also occurs in some elliptic curves
tests.
Alexander, when you said that your broken Sage installation was to blame:
Do you mean that the tests are mostly passing with your patch?
