Follow-up Comment #3, bug #25094 (project lwip):

I just wanted to test this and stumbled over a zero pbuf in tcp_connect.

Kieran, it seems that came in with tcp.c 1.91 (comment: TASK9218: add support
for TCP timestamp options). Is that code tested or why doesn't it work for

Just for information: I get an assertion failure in etharp_query:
LWIP_ASSERT("no packet queues allowed!", (p->len != p->tot_len) || (p->next
== 0));
p->next is null and p->next->(tot_)len is zero.

Note that I didn't even get to the source of *this* bug (where the header
pbuf has zero length; for me the payload pbuf has zero length)
