As we have seen the fact that something is output by *2john is no
guarantee that it cannot crash john. Many *2john's happily work on the
principle "garbage in, garbage out".
Didn't check it specifically for rar2john though.

The first thing I see when I open rar_fmt.c is that "This code is based
on the work of Alexander L. Roshal (C)". So I don't want even to look
