        }

        function E() {
        }

        const p = new Proxy(Proxy,Reflect);
        const d = {};
        const v16 = new p(E,d);
    }

    foo();

    const s = new String();
    const z = Object.defineProperty(s,Proxy,Proxy);
    const r = foo(Proxy,z,String,s);
    return r;
}

for(let i=0; i<1024; i++)
{
