Example case:

interface I

class C: I
    this(int x)
        this.x = x;
    int x;

    override bool opEquals(Object o)
        if(auto c = cast(C)o)
            return c.x == x;
        return false;

void main()
    I[] arr;
    I[] arr2;
    arr ~= new C(1);
    arr2 ~= new C(1);
    assert(arr == arr2);

Note, the opEquals isn't important, but I also want to ensure that after the
segfault is removed the correct thing is done.  Currently comparing two
interfaces for equality does not work.

I'm unsure whether this is a druntime or a dmd problem.
