I'm seeing the same thing. libpcap-1.1.1 was merged into HEAD about 4
months ago, so it's possible...
I suspect changes to libpcap's inet.c:
...although I haven't had the time to look through it thoroughly --
it's more of a "gut feeling" (if there could be such a thing regarding
C code LOL). BTW, if you give your devices descriptions, libpcap
starts to behave again; this could be a clue to the source of the bug
What do you think Rui? Any hints?
