Description:
------------
I noticed that the Error Control Operator is behaving different in php7 than php5

Test script:
---------------
<?php

function query()
{
    $myrs = null;
    $tmp = @$myrs->free_result();

    return $tmp;
}

var_dump(query());

echo "Another output";

Expected result:
----------------
NOTHING (as of php5)

Actual result:
--------------
Fatal error:  Uncaught Error: Call to a member function free_result() on null in [...][...]:6
Stack trace:
#0 [...][...](11): query()
#1 {main}
  thrown in [...][...] on line 6
