    Description:        Regression Test.

    If instance Native Object have properties that are enumerable,
    JavaScript enumerated through the properties twice. This only
    happened if objects had been instantiated, but their properties
    had not been enumerated.  ie, the object inherited properties
    from its prototype that are enumerated.

    In the core JavaScript, this is only a problem with RegExp
    objects, since the inherited properties of most core JavaScript
    objects are not enumerated.
