Oh, big surprise, it's SPARC, not x86....
Methinks that casting "&pd[offset]" to "struct rx_header *" in
"dissect_rx()" may be ill-advised, given that there's no guarantee that
"&pd[offset]" is nicely aligned on a 4-byte boundary - in fact, it
isn't, if the stack trace is to be trusted:
> Reading symbols from /usr/lib/nss_nis.so.1...done.
> Reading symbols from /usr/lib/nss_files.so.1...done.
> #0 0x82e60 in dissect_rx (pd=0x1ecab0 "\b", offset=42, fd=0x28ea00,
> tree=0x0) at packet-rx.c:156
(0x1ecab0 is aligned on a 4-byte boundary, but 42 isn't a multiple of
4), and given that many processors (e.g., SPARC processors) don't like
unaligned references.

I've attached a patch. Apply it to "packet-rx.c", and try again.
