Hi,

It looks like you need to add some NULL checks:

diff --git a/sys/netinet/in_rmx.c b/sys/netinet/in_rmx.c
index eeb7760c5cc..5f9ae967177 100644

        const struct sockaddr_in *mask4 = (const struct sockaddr_in *)mask;
-       if ((rt_flags & RTF_HOST) == 0 && mask4->sin_addr.s_addr == 0)
+       if ((rt_flags & RTF_HOST) == 0 && mask4 != NULL && 
mask4->sin_addr.s_addr == 0)
                nh->nh_flags |= NHF_DEFAULT;

/* Set nhop type to basic per-AF nhop */

                nh->nh_flags |= NHF_DEFAULT;

Else I hit a panic with this command:

sysctl net.inet.icmp.bmcastecho=1
route add -net 255.255.255.255 a.b.c.d

Where a.b.c.d is a valid IPv4 on the local network.
