Follow-up Comment #4, bug #55537 (project lwip):

Correction!!!
Mon 28 Jan 2019 01:25:29 PM UTC, comment #3:
Zero may not be correct ACK number in case pcb->unacked list is NULL. 
I suggest : 
LWIP_DEBUGF(TCP_INPUT_DEBUG, ("SYN-SENT: ackno %"U32_F" pcb->snd_nxt %"U32_F"
unacked %"U32_F"\n", ackno, 
pcb->snd_nxt, (pcb->lastack + 1)));
