PHP does not segfault anymore when trying to serialize circular references.

Note however that the serializer won't support serializing references anytime soon. If you think you cannot live without that, feel free to post a feature request.

Thanks for reporting this issue.

PHP causes httpd to segfault with the following scripts. Basically,
we feel that when the objects get restored at session_start the
references are no longer valid.

Apache Error Log:
[Thu Sep 28 19:55:57 2000] [notice] child pid 255 exit signal Segmentation fault (11)

=== file 1 ===

<?
class parentClass {
        var $child;
        var $relation = "mother";

        function makeChild() {
                $this->child = new ChildClass($this);
        }
}

class childClass {
        var $parentLink;

        function childClass(&$parent) {
                $this->parentLink = &$parent;
        }
}

session_start();
session_register("mom");

$mom = new parentClass;
$mom->makeChild();
?>

<html>
<?
echo $mom->child->parentLink->relation . "<br>";
?>
<a href="next.phtml">next</a>
</html>

=== file 2 ===

<?
class parentClass {
        var $relation = "mother";
}

class childClass {
        var $parentLink;

        function childClass(&$parent) {
                $this->parentLink = &$parent;
        }
}

session_start();
session_register("mom");

?>

<html>
<?
echo $son->parentLink->relation . "<br>";
?>
<a href="next.phtml">next</a>
</html>
