I finally debugged this issue and solved it by set TF_FIN flag on the
pcb in function tcp_send_fin() in the case where we have unsent
segments.
I wanted to make a bug report but I realized that it was already
reported:
http://savannah.nongnu.org/bugs/?33962
The patch is the same as the solution I found.
