Running the following code: class Foo { var $bar_ref; }
class Bar { var $foo_ref; } $foo = new Foo(); $bar = new Bar(); $foo->bar_ref = $bar; $bar->foo_ref = $foo; var_dump($foo); var_dump($bar); $s = serialize($foo); var_dump($s); $s = serialize($bar); var_dump($s); in PHP_4_3 results to: object(foo)(1) { ["bar_ref"]=> object(bar)(1) { ["foo_ref"]=> NULL } } object(bar)(1) { ["foo_ref"]=> object(foo)(1) { ["bar_ref"]=> object(bar)(1) { ["foo_ref"]=> NULL } } } string(58) "O:3:"foo":1:{s:7:"bar_ref";O:3:"bar":1:{s:7:"foo_ref";N;}}" string(86) "O:3:"bar":1:{s:7:"foo_ref";O:3:"foo":1:{s:7:"bar_ref";O:3:"bar":1:{s:7:"foo_ref";N;}}}" in HEAD: object(foo)#1 (1) { ["bar_ref"]=> object(bar)#2 (1) { ["foo_ref"]=> object(foo)#1 (1) { ["bar_ref"]=> object(bar)#2 (1) { ["foo_ref"]=> *RECURSION* } } } } object(bar)#2 (1) { ["foo_ref"]=> object(foo)#1 (1) { ["bar_ref"]=> object(bar)#2 (1) { ["foo_ref"]=> object(foo)#1 (1) { ["bar_ref"]=> *RECURSION* } } } } and a segfault (apache 1 sapi) or a runaway process (cli sapi).
