Whenever you define a __set or __get inside of a class within a namespace seems to undefine print_r

-----[ class.php ]-----
<?php

namespace foo
{
 class bar
 {

  function __construct()
  {
  }

  function __set($k, $v)
  {
  }

  function __get($k)
  {
  }
 }
}
?>
-----[ run.php ]-----
#!/php5/bin/php -q
<?php

 require_once "class.php";
 $a = New foo::bar;

 print "Trying ".$a->testing."\n";
 $a->abc = 123;

 print_r($a);
?>
