Nmap Development: nmap error

[MadHat <madhat () unspecific com>]

Running nmap 3.27 on FreeBSD 4.8, I am getting errors that say

assertion "tqi->sockets[probe_port_num][seq] == -1" failed: file
"targets.cc", line 599

Here is the backtrace from the core file (sorry, I am not very familiar
with gdb)

I am scanning a large number (~33K) of hosts from a file.
But the same thing seems to happens when I do something like
$ for i in `cat network-list `; do nmap $i; done
to break it up.

nmap was compiled from source.

Not sure what to do with this info, or how to fix.
