Thanks for all the debug info.  I have a few questions:

o Do this bus error happen at every execution, or is it an
  intermittent problem?
o The stack trace you sent involved a crash in the Nmap ping routine.
  Does it crash when you use -P0?  If so, please send a stack trace
  like the one you sent last time.  That can help us determine whether
  the problem is in Libpcap or the Nmap ping code.
o If you compile the tcpdump & libpcap from tcpdump.org with the same compiler,
  does it work for you or crash?

Thanks,
Fyodor
