delegates & GC allocations

[Etienne via Digitalmars-d-learn]

I've been hearing that delegates get a context pointer which will be 
allocated on the GC. Is this also true for delegates which stay in scope?

e.g.
void addThree() {
        int val;
        void addOne() {
                val++;
        }
        
        addOne();
        addOne();
        addOne();

        return val;
}

Will the above function allocate on the GC?
