Bug description:Segfault with traits and namespaces and as operator
Description:
------------
It looks like that this segfault occurs on every second request, when using
namespaces + traits + autloader + 'as' operator.
Without 'as' op it works.
Test script:
---------------
<?php
namespace app\modules\backend\rest\controllers;
class Language extends Generic
{
use \app\traits\rest\Mongo {
\app\traits\rest\Mongo::setQueryParam as _setQueryParam;
}
....
public function setQueryParam(&$query, $p, $op, $v)
{
switch ($p)
{
case 'name':
// whatever
break;
default:
$this->_setQueryParam($query, $p, $op, $v);
}
}
...
}
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
