Description:
------------
cwd is set to server root (i guess) instead of called php file's directory in __destruct()

it probably isn't server root (see results), because that would be /www on linux - on windows it is

Reproduce code:
---------------
<?php
class Foo
{
    public function bar()
    {
            echo getcwd() . "\n";
    }

    public function __destruct()
    {
        $this->bar();
    }
}
$f = new Foo();
$f->bar();
?>

Expected result:
----------------
Windows XP:
F:\htdocs
F:\htdocs

My webhoster's linux:
/www/htdocs/[some number]
/www/htdocs/[some number]

(or whatever directory the file is in)

Actual result:
--------------
Windows XP:
F:\htdocs
D:\Apache\Apache 2

My webhoster's linux:
/www/htdocs/[some number]
/
