> To reproduce the bug:

>   1. mkdir /tmp/file_corruption_bug
>   2. echo "text file 1" > /tmp/file_corruption_bug/a
>   3. dd if=/dev/zero of=/tmp/file_corruption_bug/b bs=1M count=1 seek=4099
>   4. echo "text file 2" > /tmp/file_corruption_bug/c
>   5. echo "a=/tmp/file_corruption_bug/a"  >/tmp/file_corruption_bug/path_list
>   6. echo "b=/tmp/file_corruption_bug/b" >>/tmp/file_corruption_bug/path_list
>   7. echo "c=/tmp/file_corruption_bug/c" >>/tmp/file_corruption_bug/path_list
>   8. touch /tmp/file_corruption_bug/empty
>   9. /usr/bin/genisoimage -graft-points -sort
> /tmp/file_corruption_bug/empty -udf -iso-level 3 -path-list
> /tmp/file_corruption_bug/path_list > /tmp/temp.iso
>
> In the resulting ISO file, "c" is corrupted.
> Without the "-sort /tmp/file_corruption_bug/empty", there is NO corruption.
