From: [EMAIL PROTECTED]
Operating system: Debian 2.3 (testing/unstable) with kernel 2.4.2
PHP version: 4.0.4pl1
PHP Bug Type: *Session related
Bug description: complex objects and references not saved
Here is a sample code that produces totally random results.
Elements of container become integers, switch places or even
become objects from other script run on the server before
when saving and restoring sessions.
///////////////example//////////////////////////////////////
class elt {
var $a; var $b; var $c;
function elt($a, $b, $c) {
$this->a=$a; $this->b=$b; $this->c=$c;
}
function print_elt() {
echo htmlspecialchars($this->a.' '.$this->b.' '.$this->c).'
<br> ';
}
}
class container {
var $arr;
function container() {
$this->arr=array();
}
function put($elt) {
$num=sizeof($this->arr);
$this->arr[$num]=$elt;
$this->arr['num_'.$num]=&$this->arr[$num];
}
function get_by_num($num) {
return $this->arr[$num];
}
function get_by_text($num) {
return $this->arr['num_'.$num];
}
}
session_register('x');
if (isset($x)) {
$tmp=$x->get_by_num(0); $tmp->print_elt();
$tmp=$x->get_by_text(0); $tmp->print_elt();
$tmp=$x->get_by_num(1); $tmp->print_elt();
$tmp=$x->get_by_text(1); $tmp->print_elt();
$tmp=$x->get_by_num(2); $tmp->print_elt();
$tmp=$x->get_by_text(2); $tmp->print_elt();
}
else {
$x=new container;
$x->put(new elt(1, 2, 3));
$x->put(new elt('aaa', 'bbb', 'ccc'));
$x->put(new elt('x', 'y', 'z'));
}

this 4.0.4pl1-5) with modules xml, pgsql, ldap and imap. As
server I use apache (Debian packet version 1.3.14-2.3)
