Follow-up Comment #6:
Hmm, interesting. I think I understand what you're describing. One thing
I'm not sure about is why the response from the linux stack results in an
ICMP destination unreachable - if the socket is still connected to the
address/port used for the send, surely the reply (which I assume is bound for
that address/port) will be received correctly?
However, I can see that there needs to be some protection in this function.
Implementing it in the current architecture would be tricky, and it would
become something of a special case. I'm tempted to "fix" this bug by
removing the lwip_sendto() function.
