Named native query bug?

        $flags = PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_OFFSET_CAPTURE;
        $matches = preg_split($regex, $input, -1, $flags);

        foreach ($matches as $match) {
            // Must remain before 'value' assignment since it can change content
            $type = $this->getType($match[0]);

            $this->tokens[] = array(
                'value' => $match[0],
                'type'  => $type,
                'position' => $match[1],
            );
