Ack. I didn't even think to be suspicious of the compiler.
When I turned the gcc compiler optimization for libpcap from
-O2 to -O0 (optimization off), the tcpdump started working
fine. I further narrowed it down to the -fstrict-aliasing
optimization. So I can settle on optimzations set to:
-O2
There's also the possibility of the SE Linux default configuration
shipped with FC4 causing trouble. Try disabling it and see if the error
persists?
Cheers,
Christian.

Perhaps there's a compiler bug in FC4. Libpcap isn't crashing on other
