Inconsistent output with the --seek option

It appears that radamsa gives incorrect output when used with the seek option as compared to without that option. I generated the below output with the latest version of radamsa on Github with on up-to-date Ubuntu 16.04.3:
$ printf "\x00\x00\x00\x00\x00\x00\x00\x00" | ./radamsa -s 3333 -n inf -o :8888 -v

Then trying to duplicate the last output, I do the following:
$ printf "\x00\x00\x00\x00\x00\x00\x00\x00" | ./radamsa -s 3333 -n inf -o :8888 -v -S 34
Random seed: 3333
- :8888/34 <- 127.0.0.1: 8b
and from another terminal:
$ nc 127.0.0.1 8888 | xxd
00000000: 0000 0000 0004 0000 ........
As can be seen, radamsa returns the 31st output rather than the 34th as expected. Further, comparing the output of
$ printf "\x00\x00\x00\x00\x00\x00\x00\x00" | ./radamsa -s 3333 -n inf -o :8888 -v
# Then from another terminal
$ for i in $(seq 1 34); do echo $i; nc 127.0.0.1 8888 | xxd; done
and
$ for i in $(seq 1 34); do printf "\x00\x00\x00\x00\x00\x00\x00\x00" | ./radamsa -s 3333 -n 1 -o :8888 -v -S $i; done
# Then from another terminal
$ for i in $(seq 1 34); do echo $i; nc 127.0.0.1 8888 | xxd; sleep 1; done # sleep needed to make sure radamsa is up
It appears that test case 16 is the first one to differ.

Great report, thanks! I'll have a look. Possibly the seek option doesn't play too well with the checksum filter, which is on by default in git...

Fixed in trunk. Seek was not applying the uniqueness filter. Feel free to reopen if you can still reproduce this somehow.
Thanks for the report.
