>Description:

I get a core dump from npfctl(8) after loading the configuration file
and starting the filter.

The configuration is derived from /usr/share/examples/npt/soho_gw-npf.conf

No network traffic occurs on the external interface after this point.

>How-To-Repeat:

# npfctl reload
# npfctl start
# npfctl show
Filtering:      active
Configuration:  loaded


map pppoe0 dynamic any -> 81.187.158.176 pass from { 192.168.0.0/24 } 
assertion "obj" failed: file "/u1/src/common/lib/libprop/prop_object.c", line 
1075, function "prop_object_release"
Abort trap (core dumped)
