Bug description: var_dump() doesn't completely protect against infinite looping
Description:
------------
Calling var_dump() on a closure that references itself results in an
infinite loop.
Reproduce code:
---------------
<?php
$f = function () use (&$f) {};
var_dump($f);
?>
Expected result:
----------------
object(Closure)#1 (1) {
["static"]=>
array(1) {
["f"]=>
&object(Closure)#1 (1) {
["static"]=>
array(1) {
["f"]=>RECURSION
}
}
}
}
Actual result:
--------------
object(Closure)#1 (1) {
["static"]=>
array(1) {
["f"]=>
&object(Closure)#1 (1) {
["static"]=>
array(1) {
["f"]=>
&object(Closure)#1 (1) {
["static"]=>
array(1) {
["f"]=>
<repeats forever>
