Thanks for the report, Sebastian.  This is definitely an Nmap bug
related to a combination of scanning port zero and OS scan, but after
looking into the code, I think this only affects the old OS detection
system.  Since I hope to get rid of that 1st generation system
completely, it probably isn't worth fixing and testing.  Though if
someone wants to, I'd certainly accept a patch.  And if you are able
to reproduce this with -O2 (sencond generation system), please post
the log.

Thanks!
