PHP Bug Type: Session related
Bug description: Unserialize crashes on multiple objects, stored in session explicitly
Description:
------------
PHP crashes on session_start() if object "foo" references to object "bar"
and both "foo" and "bar" are put into session explicitly each into it's
element.
The example below will work if we comment line:
$_SESSION['bar'] = $bar;
the only one "foo" is put to session explicitly and "bar" is also put, but
as a member of "foo".
Reproduce code:
---------------
<?
class foo {
public $bar = NULL;
}
class bar {}
//=============================[]
$foo = new foo();
$bar = new bar();
$foo->bar = $bar;
session_start();
$_SESSION['foo'] = $foo;
$_SESSION['bar'] = $bar; // it will be all right, if we comment this
session_write_close();
session_start(); // crashing here
echo "OK";
?>
Expected result:
----------------
OK
Actual result:
--------------
