Description
The following seems bad. It was revealed by the change in doctest framework at #12415. That ticket introduces a workaround (just resetting opt['red_tail']
to True).
sage: from sage.libs.singular.option import opt sage: opt['red_tail'] True sage: Rlocal.<x,y,z> = PolynomialRing(QQ, order='ds') sage: opt['red_tail'] False

J.groebner_basis(mult_bound=100)
also resetsopt['red_tail']
, butJ.groebner_basis()
doesn't.
