Follow-up Comment #1:

I don't get the same problem you observed when connecting via telnet and
pressing enter twice: I get two distinct pbufs. I guess you have a problem
somewhere with your netif driver that results in getting the same pbuf twice
here.

To detect such problems, I've added an assert to pbuf_cat() that h and t are
not the same: although that doesn't every loop, it might detect this bug
here.

Good luck with finding your actual bug! ;-)
