    Description

      function func(arr) {
          try {
             print(arr.toString());
          } catch (e) {
             print(e.stack);
          }
      }

      var arr = ["hello", "world"]

      func(arr);

      var global = loadWithNewGlobal({
         name: "t",
         script: <<EOF


      function func(arr) {
         try {
             print(arr.toString());
         } catch (e) {
             print(e.stack);
         }
      }

      var arr = [1, 2, 3];

      func(arr);

      delete Array.prototype.toString;

      func(arr);
      this;
      EOF
      });


      Expected:

      hello,world
      1,2,3
      [object Array]

      Output seen:

      hello,world
      1,2,3
      TypeError: Cannot call undefined
      at func (t:5)
      at <program> (t:17)
      at <program> (test.js:13)


      After Array.prototype.toString is deleted, Object.prototype.toString should be visible - callsite that calls array.toString shoud be invalidated and re-resolved to use Object.prototype.toString. This does not happen when loadWithNewGlobal is used.
