Hello all, I am responding to my own post, but thought I'd share this with the list all the same.

I just found a bug in a rarely-used piece of my code which allowed me to call pcap_sendpacket() with an obviously illegal length of 1528 bytes. Depending on what pcap had done prior to getting this illegal call, any/all of the above symptoms could occur. Gee, tracking this down reminded me of the days of watching MS-DOS gracefully signal a fatal exception: By freezing entirely, or instantly re-booting!
