Bug description: $this reference is bad during __wakeup
Description:
------------
This is a re-open of Bug #13968.
I can still see the same issue happening with PHP 4.3.10. Just like the
previous poster (in bug #13968), I cannot reproduce this with simple code.
However, the general idea is this:
class Base
{
var $resource = new Resource();
function __wakeup()
{
// In a saved session, the resource lost relevance, so we reopne
it:
$this->resource = open_resource(); // <-- this corrupts Thing's
another_member
}
};
class Child extends Base
{
};
class Thing
{
var $member;
var $another_member; // <-- when wakes up, this is equal to the
Resource we open in Base's __wakeup.
function Thing()
{
$this->member = new Child();
$this->another_member = 12345;
}
};
