Sendto errors in OpenBSD 3.3

[Eric <eric-list-nmap () catastrophe net>]

I'm running the latest version of nmap on the following platform.

# uname -a
OpenBSD foo 3.3 20030908#0 i386

# nmap -sS -v -PT22,25,80,135,445 -PM -PE -g 53 -T 4 10.10.10.0/25

Host 10.10.10.0 seems to be a subnet broadcast address (returned
1 extra pings).  Still scanning it due to ping response from its own IP.

The last portions of the --packet_trace show the following..

I reported this a while back under 3.21 and never got a recent
version working. The OpenBSD 3.00 package works well and doesn't
this problem.

If there's something I can do to help fix it, please lemme know.

Thanks
