Apc engine bug

In apc.inc in apcCacheEngine::set (line 111)

      // Attempt to store full key and value 
      if (isset($ttl)) {
        $result = apc_fetch($this->key($key), $data, $ttl);
      }
      else {
        $result = apc_store($this->key($key), $data);
      }

did you mean :

      // Attempt to store full key and value
      if (isset($ttl)) {
        $result = apc_store($this->key($key), $data, $ttl);
      }
      else {
        $result = apc_store($this->key($key), $data);
      }
