Re: Using -O with DMD seems to produce non-random values.

[Kagamin via Digitalmars-d-learn]

how this works?

double[] generateValues(ref Random rand, int l)
{
        auto values = new double[](l);
        foreach (ref val; values)
        {
                auto value = 1;
                if (uniform(0, 2, rand))
                {
                        value = value * -1;
                }
                val = value;
        }

        return values;
}
