With gcd : 'spmod and algebraic : true, the calculuation gets stuck:
(%i1) k : (1+z^2)^4/ (1+z^4)^4$
(%i2) integrate(k,z,0,inf), gcd : 'spmod, algebraic : true;
Maxima encountered a Lisp error:
But with gcd : 'spmod, algebraic : false, the result is wrong:
(%i3) integrate(k,z,0,inf), gcd : 'spmod, algebraic : false;
(%o3) 0
