More like bug #29423
This issue popped up in PHP 4.3.10, code that worked fine with previous
releases started segfaulting when doing things like:
function __wakeup() {
global $a;
$a[] =& $this;
}

See also bug #25975, isn't this pretty much same issue?

ZE2 problem, can't reproduce with PHP 4.3.3.

after commenting out line 2543 of Zend/zend_execute.c the bug seems to
be fixed.. but i have no idea if that solution induces more other
problems...

Description:
------------
Its mainly an internal problem...
if i use zval_add_ref(&getThis()); in the __wakeup() method
it will be ignored at all... after unserializing the refcount of my
object is allways set to "1" :(
its reproduceable even through this php-code:
Reproduce code:
---------------
<?php
$a=array();
class x {
function __wakeup() {
global $a;
$a[]=$this;
}
}
$t=new x();
var_dump($t);
$t=unserialize(serialize($t));
unset($a);
var_dump($t);
?>
Expected result:
----------------
object(x)#1 (0) {
}
object(x)#1 (0) {
}
Actual result:
--------------
object(x)#1 (0) {
}
UNKNOWN:0
or:
object(x)#1 (0) { }
Fatal error: Trying to access invalid object in ... on line 15
