// Whenever we enter a with-scope, we copy the context. This in itself is fine

// (contexts may escape), but when leaving a with-scope, we currently also copy

// the context instead of reverting to the original. This does not work because

// inner functions may already have been created using the original context. In

// the failing test case below, the inner function is run in the original context

// (where x is undefined), but the assignment to x after the with-statement is

// run in the copied context:

var result = (function outer() {

 with ({}) { }

 var x = 10;

 function inner() {

   return x;

 };

 return inner();

})();

assertEquals(10, result);
