Follow-up Comment #3, bug #28241 (project lwip):

I can see what you mean with the GT -> GEQ change, but I don't understand
that FIN change:

+ /* cseg with FIN already processed */ 
+ if (TCPH_FLAGS(next->mpTcpHdr) & TCP_FIN) { 
+ TCPH_FLAGS_SET(cseg->tcphdr, TCPH_FLAGS(cseg->tcphdr) & ~TCP_FIN); 
+ }

This reads to me as:
 if (old packet has FIN set) {
   remove FIN from new packet's flags;

Can you explain why you'd want to do that?
