[lwip-devel] [bug #25094] Zero-length pbuf

[Simon Goldschmidt]

Follow-up Comment #7, bug #25094 (project lwip):

I think the change was that previously, the options in connect were enqueued
as data, while now they are enqueued as options. Without the
TCP_WRITE_FLAG_COPY, this results in allocating a _ROM pbuf for the data
(although seglen is 0 - this is the error) and a _RAM pbuf for the headers.

The patch Roy just attached seems like the way to go for me.
