Bug description: crash serializing objects with recursive references
Description:
------------
Php craches when trying to serialize objects with deep recursive
references. It only works with two objects, each having a reference to the
other. When using three or more objects in a circular chain, it crashes
badly.
I have written a simplified example for help.
Thanks.
PS.
I have found this bug ( and bug reports on it ) in the past but it
doesn't seem to be fixed. Maybe it has reapered in php5.
Reproduce code:
---------------
<?
class A
{
public $b;
}
class B
{
public $c;
}
class C
{
public $a;
}
$a = new A();
$b = new B();
$c = new C();
$a->b = $b;
$b->c = $c;
$c->a = $a;
echo serialize($a);
?>
Expected result:
----------------
some serializaton string
Actual result:
--------------
