--- Comment #4 from Walter Bright <bugzilla at digitalmars.com> ---
A smaller test case:

void qux()@safe{
    int* foo(return scope int* x)@safe{
        int* bar(return scope int* y)@safe{
            return x; (*)
        }
        return null;
    }
}

(*) compiler should complain that x is escaping via return
