        function check() {
            try { foo; return true } catch (e) { return false }
        }

        // This should alternate b/w false and true for all iterations
        // but after 16 iterations, both prints print "true"
        // => ReferenceError is not thrown in "check" method for "foo"
        // access after "foo" access becomes megamorphic
        for (var x = 0; x < 40; x++) {
            delete this.foo;
            print(check());
            foo = 44;
            print(check());
