I ran into an issue using libpcap and tcpdump.
Whenever I enter a filter tcpdump segfaults:
i.e.:
works fine :
#tcpdump
segfault
#tcpdump port 80
That's a rather common filter, I suspect. :-)
I.e., if this were a libpcap bug, unless it's a very new one, it would
have been discovered by now - and I don't see it with
$ gcc --version

with the current CVS code, so I suspect it's not something that showed
up recently.
What happens if you compile libpcap with GCC's optimizer turned off? I
suspect this is a bug in the version of GCC in FC4.
