Looks like a libc bug.
In fact, I seem to remember recently seeing, either in tcpdump-workers
or one of the Ethereal mailing lists, a discussion where it was
eventually concluded that there was, indeed, a bug in some versions of
GNU libc - I think it might have been in the code that looked up
Ethernet addresses in the Ethernet address <-> host name data base -
that caused crashes. Unfortunately, I don't remember which list it was
in, or which message it was.
