Description:
------------
I hope this fixes the majority of the 900 memleaks we currently have in our application

Test script:
---------------
class sa
{
    public static function coerceTo(string $type, array $array): array
    {
        return self::_coerceToString(...array_values($array));
    }

    protected static function _coerceToString(string ...$strings): array
    {
        return $strings;
    }
}

sa::coerceTo("string", ['nl' => 0.9, 'be' => 0.2]);


Actual result:
--------------
Zend/zend_string.h(141) :  Freeing 0x00007fb91a281300 (224 bytes), script=/tmp/memleak.php
Last leak repeated 1 time
