Description of Problem:

Some cases of generic inheritance and virtual calls produce unmanaged stack
overflows at creation time of these inherited objects.


Steps to reproduce the problem:

Run

class Program {
static void Main() { var x = new holderJ(); }

class holderJ {
    public virtual TValue Value<TKey, TValue>() {
        return target.Value<TKey, TValue>();
    }

    holderJ target = new actualHolderJ<int>();

    class actualHolderJ<T> : holderJ {
        struct holder<TKey, TValue> {
            public static TValue Val;
        }

        public override TValue Value<TKey, TValue>() {
            return actualHolderJ<T>.holder<TKey, TValue>.Val;
        }
    }
}
}


Actual Results:

Unmanaged stack overflows


Expected Results:

no output, no error


How often does this happen? 

every time
