Thanks, ive checked in your patch.

What options were you using to get the segfault ?

The bug i see it fix is the following

Before patch
$ ./busybox tail -n 2 AUTHORS TODO
==> AUTHORS <==
    devfsd and size optimizations in strings, openvt, chvt, deallocvt,
hdparm and fdformat.


==> TODO <==
$

After patch
$ ./busybox tail -n 2 AUTHORS TODO
==> AUTHORS <==
    devfsd and size optimizations in strings, openvt, chvt, deallocvt,
hdparm and fdformat.


==> TODO <==
----

$

Note the first example didnt have any lines under TODO.
