Interesting. It seems gif isn't passing anything back at all. Can you verify
that the routes for the addresses you're pinging traverse gif0? I'd
probably also try csjp@'s bpfstat tool to get a closer look at what's
going on in bpf.

Also try assigning a local address to an instance of gif on the affected
system and pinging a destination through it using the -r and -S options
whilst running tcpdump to be sure.

Can you post the revision(s) of the source files? e.g.:
...and uname -a?

Hope this helps,
