This is a regression in the upgrade 4.1.1p2 -> 4.1.1p3:
SINGULAR / Development A Computer Algebra System for Polynomial Computations / version 4.1.1 0< by: W. Decker, G.-M. Greuel, G. Pfister, H. Schoenemann \ Feb 2018 FB Mathematik der Universitaet, D-67653 Kaiserslautern \ > ring R = integer,(x),dp; > gcd(2*x, 2); 1
The gcd in Z[x] is well-defined: the answer should be 2.
