[lwip-devel] [bug #62857] sendmsg(), if called with last item in msg_iov array to have .iov_len=0, build pbuf chain which cannot be cloned

[Simon Goldschmidt]

Follow-up Comment #1, bug #62857 (project lwip):

>From the description below, I'm tempted to change pbuf_clone() to just skip
zero-sized pbufs (if anything has been copied yet). I guess that would be
enough to fix this?
