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." defect closed major sage-8.2 symbolics fixed Ralf Stephan Travis Scrimshaw N/A 41ea6818fb163a2f17cb8152c686f25a384f0edf 41ea6818fb163a2f17cb8152c686f25a384f0edf #23950
