... operator exception on special version 5.6.6

i report it because i can't google it.


Test script:
---------------
<?php
    // return $instance->$method(...$args);
    class Abc{
        protected function prefix($parameters) {
            echo "xxxxxxxxxxxxxxxx\n";
            var_dump($parameters);
        }

        public function __call($method, $args) {
            echo "****************\n";
            var_dump($method, $args);
            // debug_zval_dump( $args );
        }
    }

    $instance = new Abc;

    $args = ['api'];

    $instance->prefix(...$args);
    echo 'phpversion: ', phpversion(), "\n";
?>

Expected result:
----------------
==========================
output on 5.6.5: 
****************
string(6) "prefix"
array(0) {
}
phpversion: 5.6.5

==========================
output on other version not 5.6.5 : 
****************
string(6) "prefix"
array(1) {
  [0]=>
  string(3) "api"
}
phpversion: 5.6.24-1+b1

Actual result:
--------------
==========================
output on 5.6.5: 
****************
string(6) "prefix"
array(0) {
}
phpversion: 5.6.5

==========================
output on other version not 5.6.5 : 
****************
string(6) "prefix"
array(1) {
  [0]=>
  string(3) "api"
}
phpversion: 5.6.24-1+b1

Sorry, it's not a bug, it seems that phalcon extension changes the behavior of __call.
<?php
    // return $instance->$method(...$args);
    class Abc{
        protected function prefix($parameters) {
            echo "xxxxxxxxxxxxxxxx\n";
            var_dump($parameters);
        }

        public function __call($method, $args) {
            echo "****************\n";
            var_dump($method, $args);
            // debug_zval_dump( $args );
        }
    }

    $instance = new Abc;

    $args = ['api'];

    $instance->prefix(...$args);
    echo 'phpversion: ', phpversion(), "\n";
    echo extension_loaded('phalcon') ? Phalcon\Version::get() : 'no phalcon';
?>

===========================
test output:
