What will be if ur models extends MY_Controller?

Few days ago I was make some changes in my code before going to sleep.
By mistake I make this code: models extends MY_Controller.

MY_Controller have standart code:

class MY_Controller extends CI_Controller {
public data = array();
public function __construct()
{
parent::__construct();
$this->data['blabla'] = blabla;
}
}

I don't have xdebug, and when I was run php -S localhost:2222 (php version 5.5) I saw only one error "segmentation fault". If u try to search what this mean, u will find thousands answers how fix it. Some peoples recomend check memory or remove php-mysql.
xdebug don't help me fix errors, and I was researched all last modifed files to find my mistake.

Don't waste your time trying to understand why it doesn't work and just fix your code. A model is not supposed to extend a controller. Also, I doubt the segmentation fault error is caused by your code. Because this error means PHP has crashed. It may be a bug in PHP itself or something is wrong with your server.
