Floating point exception when factoring over QQ['x,y'] Can reproduce this on sagenb.org so probably this time the fault are not my cpus:
sage: K.<x,y>=QQ[] sage: pp=6*x^5*y + 15*x^4*y^2 + 20*x^3*y^3 + 15*x^2*y^4 + 6*x*y^5 - 12*x^5 - 60*x^4*y - 120*x^3*y^2 - 120*x^2*y^3 - 60*x*y^4 - 12*y^5 + 60*x^4 + 240*x^3*y + 360*x^2*y^2 + 240*x*y^3 + 60*y^4 - 160*x^3 - 480*x^2*y - 480*x*y^2 - 160*y^3 + 240*x^2 + 480*x*y + 240*y^2 - 192*x - 192*y + 64 sage: factor(pp) ...multi_polynomial_libsingular.so in sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular.factor (sage/rings/polynomial/multi_polynomial_libsingular.cpp:25414)() RuntimeError: Floating point exception -- You received this message because you are subscribed to the Google Groups "sage-support" group.
