Bug description:Method that returns string returns UNKNOWN:0 instead
Description:
------------
We upgraded to php 7.1 and noticed some tests are failing. This method
call returns UNKNOWN:0 since the upgrade. If we remove method return
type, then we get expected string that is really returned by the
method.
I noticed that this "sometimes" doesn't happen for the first run, so it
might be opcache related.
I noticed, removing self::CZ and changing it to CountryMapping::CZ fixes
the issue. Also removing return type fixes it as well.

Test script:
---------------
<?php
namespace Core\Bundle\Service\Property\Room\Rooms;
class CountryMapping
{
const CZ = 'CZ';
const EN = 'EN';
public function get(string $countryIsoCode = null) : string // Works
correctly if return type is removed
{
switch (strtoupper($countryIsoCode)) {
case 'CZ':
case 'SK':
return self::CZ; // Works correctly if changed to
CountryMapping::CZ
default:
return self::EN; // Works correctly if changed to
CountryMapping::EN
}
}
}
$mapping = new CountryMapping();
var_dump($mapping->get('CZ'));
Expected result:
----------------
string(2) "CZ"
Actual result:
--------------
UNKNOWN:0
