Can't change users roles after upgrade

[nixargh]

I done upgrade from '2.1.25' to '2.1.26 + #1550'.
Also I upgraded from php5.4 to php5.5, maybe it's related somehow.

Under user admin my UI got stuck when I tried to do some change at 'Manage User' page.
Apache error was:
PHP Fatal error: Can't use function return value in write context in /var/www/password..domain.com/sources/users.queries.php on line 30, referer: https://password..domain.com/index.php?page=manage_users

Please consider to add my monkey patch or maybe you know the better way.
Here is patch I used to make it works: monkey patch

Strange that you get this error and not others.

I totally understand why you have this error but don't understand why on my test environment, it is not shown. I'm using php 7.0.1 and .5.6.19.

I've changed this .

Thanks for reporting
