19// replace $a - the recursion detection seems to be causing $a to be not an array here, maybe its internally a pointer
20// replacing $a with a new array() allows this test to still check for 2 things
21//  1. recursion detection in &$a;
22//  2. recursion detection in adding $a to itself and then serializing $a
23// the one thing the test won't check is using $a as an array after doing &$a; which isn't really a wddx problem.
24$a = array();
25$a['x'] = 'foo';
26$a['x'] = $a;
