Antigen produces non-deterministic outputs causing false negatives

[tannergooding]

Antigen will occasionally produce code similar to:

public static int Main(string[] args)
{
    return Antigen();
}

public static int Antigen()
{
    new TestClass().Method0();
    return string.Join(Environment.NewLine, toPrint).GetHashCode();
}

This then causes the following failure:

Debug: -413924943

Release: 533722869




GH title text:
OutputMismatch

This code will always fail because string.GetHashCode() is non-deterministic across runs, it is only deterministic within the context of a single run. It would be better if this were to print and compare the contents of toPrint instead.
