    Description

      After execution following code:
      b = 201000 with Qt 5.0.2 (correct)
      b = 4 with Qt 5.2.1, 5.3beta1 (wrong)

        Component.onCompleted: {
      var a = [100500];
      var b = 2 * a[0] | 0;
      console.log("b = ", b);
  }

      If I don't access array by index everything seems to be OK
