Reduced test case:

abstract class base
{
    static if (! __traits(isVirtualMethod, foo))
    {
    }

    private bool _bar;
    public void foo();
}

class derived: base   // line 44
{
    public override void foo() {}
}

void main()
{
    printf("vtbl = %d\n", typeid(derived).vtbl.length -
                          typeid(Object).vtbl.length);
    // With 2.062, prints "1"
    // With 2.063, prints "2"
}

Problematic deprecation message:
test.d(44): Deprecation: class test.derived use of test.base.foo() hidden by
derived is deprecated. Use 'alias base.foo foo;' to introduce base class
overload set.
