Curl_ftp_done() isn't called before the connection is closed, so

    if((-1 != data->set.infilesize) &&
       (data->set.infilesize != *ftp->bytecountp) &&
       !data->set.crlf) {
      failf(data, "Uploaded unaligned file size (%d out of %d bytes)",
            *ftp->bytecountp, data->set.infilesize);
      return CURLE_PARTIAL_FILE;
    }

(that return CURLE_PARTIAL_FILE) stopped executing the function and
clean closing the socket which sometimes caused that some bytes at the
end of the file wasn't delivered.

I commented this "if" out.

That set.infilesize is many times set by another variables which are
not int64. Unfortunately, it is a huge amount or variables. Many of
them are defined as a part or some function, some of them cannot be
retyped (as filesize_t). I hope someone who knows the code better than
me shall fix this ;-)
