Mad_Flute Stops reciving after 65535 Blocks

Question

I am playing with a flute protocol application called mad_flute. http://mad.cs.tut.fi/

Everything works well except when I try to send a file larger then 30GB. (Or more than 65536) blocks. The application has 1 sending part and 1 reciving. The sending side seams to be working and you can see it send all blocks "88462/88462 Source Blocks sent (TOI=1 SBN=88461)" Reciver side always stops at "65536/88462 Source Blocks decoded (TOI=1 SBN=65535)"

I did find one INT16 variable in the source but adjusting that did not resolve the issue.

Next, I found a logical "Delta2 = 65535 - Delat1;" part in the mad_rlc.c and bumped that value up but still reciver stops at "65536/88462 Source Blocks decoded (TOI=1 SBN=65535)"

Source can be downloaded form here: http://mad.cs.tut.fi/download/mad_fcl_v1.7_src.zip

Any pointers from a C king/queen would be amazing.

    return 0;
}

/* This is not the one we're waiting for... */
if(s->rlc->rx_wait_for[layer] < seqid) {

    Delta1 = seqid - s->rlc->rx_wait_for[layer];
    Delta2 = 65535 - Delta1;

    if(Delta1 < Delta2) {

        late_limit = RLC_MAX_LATES;

        for(i = s->rlc->rx_wait_for[layer]; i < seqid; i++) {
