-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 makes sure we don't hang when setting cyclic prototype values: http://bugs.webkit.org/show_bug.cgi?id=6985
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
 
 
-PASS [42].concat() is [42]
+PASS o1.__proto__ = o3; threw exception Error: Cyclic __proto__ value.
+PASS ({}).hasOwnProperty.call(o1, '__proto__') is false
+PASS ({}).hasOwnProperty.call(o1, '__proto__') is true
+PASS Object.getPrototypeOf(o1) is null
 PASS successfullyParsed is true
