Calling through an interface invokes the wrong method:

interface ITwo

interface IThree : IOne, ITwo

class Three : IThree

        void one ()

        void three ()
        {
                printf ("three\n");
        }
}


void main()
{
        IThree three = new Three;

        three.one();
        three.two();
        three.three();
}

print the following:

one
one
three

This clearly makes interfaces unusable at a rather fundamental level. Would
very much appreciate a fix asap.

produces this (incorrect) output instead:

two
two
three

I suppose if there's honor amongst thieves then there should be symmetry
within bugs. Can you perhaps give some indication when this might be
resolved please?
