Oops, i missed one important point: the segfault occurs if an exception
is thrown ;) Sorry, it's too late for me today.

Description:
------------
A circular reference causes gc_collect_cycles() to segfault. I know
there is another bug that looks similar (#36482) but i think this is a
far better (because simpler) test case.
Reproduce code:
---------------
<?php
class foo {
public $foo;
public function __destruct() {
throw new Exception("foobar");
}
}
$f1 = new foo;
$f2 = new foo;
$f1->foo = $f2;
$f2->foo = $f1;
unset($f1, $f2);
// triggers a segfault
gc_collect_cycles();
Actual result:
--------------
$ php test.php
Segmentation fault
