Hey Damian,
Just checked with latest master.
I confirm that the problem is indeed solved.
I'm closing this bug.
Thanks @nikic!

This sounds like the same problem as bug #73273. Can you try a build of master to confirm whether
@nikic's fix solves this?

We have the same behaviour when we copy a temp variable ($sessionCopy) in $_SESSION.

It affects all versions starting with 7.0.
If I copy the $_SESSION variable in another variable ($sessionCopy) and then I call session_decode,
I do not expect $sessionCopy to be impacted by the call to $_SESSION.
Yet, in PHP 7.0+, $sessionCopy is also modified.
Test script:
---------------
<?php
session_start();
// $_SESSION is empty so $oldSession is empty too now.
// I expect copy to be by value, not by reference so anything impacting $_SESSION should not impace
$oldSession.
$oldSession = $_SESSION;
session_decode('id|i:1;');
var_dump($_SESSION);
var_dump($oldSession);
Expected result:
----------------
I expect $_SESSION and $oldSession to be different.
Actual result:
--------------
In PHP 7+, $_SESSION and $oldSession are equal.
