--- Comment #13 from Martin Nowak <code@dawg.eu> ---
See Issue 9978 for why we allow to override interface functions. The given code should work.

--- Comment #14 from Martin Nowak <code@dawg.eu> ---
As a workaround one can redeclare the interface methods in the abstract class.

----
interface I
{
    void foo();
}

abstract class A : I
{
    override void foo();
}

class B : A
{
    override void foo () {}
}
----

Note that this bug and the workaround also applies to implicit abstract classes.

----
interface I
{
    void foo();
}

class A : I
{
    abstract override void foo();
}

class B : A
{
    override void foo () {}
}
----
