It would immensely helpful to have a backtrace of the fault. IF you can
compile it with debugging symbols (add -g to the CFLAGS) and recompile.
Then run it under gdb (r -d) and do a bt-full when it dies.

I dont have any idea what you want to accomplish by prefering something,
then preferring nothing. Remove the first prefer statement -- it is
bogus anyway as you can't reprefer something you can't represent (that
address isn't in your VirtualInterfaces section).

That's the threaded spread library.

Please try upgrading to the latest CVS version.

Also make sure you disable threading support... Looks like it enable in
your build. After running configure you should have seen something
like this:

echo ""
echo " *************************** WARNING
*******************************"
echo " FreeBSD threading has shown to cause serious problems in
wackamole."
echo " It appears that you have threading enabled. This is highly"
echo " experimental. Please consider disabling threading entirely by"
echo " rerunning configure with the --with-threads=no option."
echo "
