And I would be happy with an eventual automated ban there. Unlike the_index, it comes from the system, so it's in the same boat as strcpy() etc. That said, I think it's less urgent. The urgent problem fixed by the patch you linked was the use of strcpy() to overflow the buffer. Without that, it just becomes a normal bug where we do not handle long paths well on some operating systems. -Peff
