Doctest improvements to symbolic GCD
The following all give errors:
sage: gcd(II*x, x^21)
sage: gcd(I+I*x, x^21)
sage: alg = SR(QQbar(sqrt(2)+I*sqrt(3)))
sage: gcd(alg+alg*x, x^21)
sage: gcd(algalg*x, x^21)
sage: sqrt2 = SR(QQbar(sqrt(2)))
sage: gcd(sqrt2+sqrt2*x, x^21)
sage: gcd(sqrt2sqrt2*x, x^21)
This is fixed in Pynac master and should be doctested here.
Note that although Singular supports algebraic GCD Pynac uses Singular only in rational mode. Use a dedicated polynomial ring instead of symbolics if you want algebraic GCD.

Can you reproduce this, I have with 8.1beta9:
