-Tests the behavior of Array.prototype.concat while the array is having a bad time due to one of the elements we are concatenating.
+This test checks that toString() does not have a problem when an object has itself as a property.
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
 
 
-PASS [42].concat() is [42]
+PASS var array = []; array[0] = array; array + '' is ''
+PASS var error = new Error; error.name = error; error.message = error; error + '' is ''
+PASS var regexp = /a/; regexp.source = regexp; regexp + '' is '/a/'
 PASS successfullyParsed is true
 
 TEST COMPLETE
