    [driver] Give a message error when some tool finish unexpectly
    
    When a tool finishes without calling exit() or _exit() it means
    that it worked wrong, usually a segmentation fault, and it is
    very probable that without a message error. This patch adds
    an "internal error" to show some error to the user.
