Mathematica : Integrate bug? Generate conditions.

    Please try:
    Integrate[((x - 1)^2/x) (1 - y), {y, 0, 1}, {x, 0, 1}]
    Integrate[((x - 1)^2/x) (1 - y), {x, 0, 1}, {y, 0, 1}]

    on your version. My Options[Integrate] GenerateConditions-> Automatic.

    In the first case, it gives -3/4, the second is divergent.

    For some reason when the integration order is changed, it changes whether it "generates" the conditions required for the integral. If you force assumptions on the variables, then its fine and both diverge.

    Is this just my build? Or does everyone have this.
