Not really an error but it contains one password of 28 characters while
the maxlength is 27.

For some reason, that exact command (just other paths) does not segfault
here. This one does:
$ cat rockyou.lst | ../run/john -stdin -fo=nt ../../pw-fake-nt100k
It works just fine if using -wo:rockyou.lst instead.
I just reviewed Jim's changes to wordlist.c. I can't see that -stdin
mode is different at all from earlier code (just some if clauses) so
maybe that was not what introduced it. But I have narrowed it down to
being introduced by *something* in the 0004 patch. Might be a problem
with NT_fmt. I'll do some real debugging.
