Description
function func(arg) {
  (function() { print(eval('this')); }).call(arg);
}

func(this);
func({});
func({ toString: function() "foo" });
func(new java.lang.Vector());

Expected:

[object global]
[object Object]
foo
[]    

Last one is toString value on empty Vector instance


Actual output:

[object global]
[object Object]
foo
[object global]
