I can reproduce this with ./bin/test --seed=13604685
sympy/polys/tests/test_polyroots.py
I put in some print statements, and it seems that roots is returning
{1: 1, y/2 - sqrt(8*x**2 + y**2 - 2*y + 1)/2 + 1/2: 0, y/2 +
sqrt(8*x**2 + y**2 - 2*y + 1)/2 + 1/2: 0} when it should be returning
{1: 1, y/2 - sqrt(8*x**2 + y**2 - 2*y + 1)/2 + 1/2: 1, y/2 +
sqrt(8*x**2 + y**2 - 2*y + 1)/2 + 1/2: 1} (the difference is the
values).
