The debian libapache2-mod-php5 (5.4.4-14) is certainly not thread-safe.

It seems, or it does?
Is this a ZTS build?
Thanks.

The only thing is a DBG v4.6.4 installation, but it seems to make no difference
if it is activated or not.

Can't reproduce.
Do you have any special extensions loaded? If so, see if that also happens
without them loaded.

maybe due to the serialize

Description:
The transactions array of the $_SESSION variable is initialized only once.
If you repeat the invocation of the script. After a while the array contains
some
elements that are no more Objects of class S but references (for example
r:5607;).
Test script:
---
?php
class S implements \Serializable {
protected $data = [];
public function __construct() {
for ( $i = 0; $i = mt_rand(4, 7); $i++ ) {
$this-data[] = mt_rand(0, 50);
}
}
public function serialize() {
return serialize($this-data);
}
public function unserialize($data) {
$this-data = unserialize($data);
}
}
session_name(testS);
session_start();
if ( empty($_SESSION[transactions]) ) {
$_SESSION[transactions] = [ new S(), new S(), new S(), new S() ];
}
echo serialize($_SESSION);
?
Expected result:
Example (first call):
transactions|a:4:{i:0;C:1:S:76:{a:8:
{i:0;i:9;i:1;i:24;i:2;i:23;i:3;i:46;i:4;i:29;i:5;i:4;i:6;i:44;i:7;i:14;}}i:1;C:1:
S:51:{a:5:{i:0;i:11;i:1;i:45;i:2;i:12;i:3;i:10;i:4;i:21;}}i:2;C:1:S:59:{a:6:
{i:0;i:47;i:1;i:5;i:2;i:40;i:3;i:35;i:4;i:29;i:5;i:14;}}i:3;C:1:S:58:{a:6:
{i:0;i:20;i:1;i:20;i:2;i:7;i:3;i:44;i:4;i:7;i:5;i:27;}}}
Actual result:
--
Example (after some roundabout 50 calls):
transactions|a:4:{i:0;r:5607;i:1;r:5617;i:2;r:5624;i:3;r:5632;}
