Roundcube 1.1.4 internal error 500 on PHP 7, CentOS 6.x

[zEitEr]

Hello,

The recent PHP 7.0.4 as well as PHP 7.0.3 with Roundcube 1.1.4 gives us an error:

catchable fatal error: session_regenerate_id(): Failed to create(read) session ID: user (path: /var/www/tmp) in /var/www/html/roundcubemail-1.1.4/program/lib/Roundcube/rcube_session.php on line 436

it is:

    /**
     * Generate and set new session id
     *
     * @param boolean $destroy If enabled the current session will be destroyed
     */
    public function regenerate_id($destroy=true)
    {
        session_regenerate_id($destroy);

       $this->vars = null;
        $this->key  = session_id();
       return true;
    }

in /var/www/html/roundcubemail-1.1.4/program/lib/Roundcube/rcube_session.php

if to comment line

// session_regenerate_id($destroy);

Roundcube starts to work as usual. And it works fine with PHP 5.6. Changing session path from /var/www/tmp to /tmp does not change the situation.
Anybody else has the error? Or know how to fix it securely?


p.s. The code

<?php
session_start();
session_regenerate_id();
echo session_id()."<br>";

works fine without errors if to put it under /var/www/html/roundcubemail/ into /var/www/html/roundcubemail/test.php

You need to use Roundcube beta 1.2 in order to use PHP 7
