>Description:
In Fact, in FreeBSD, when a core with the active "VIMAGE" option, and a rule in pf.conf overload, the freebsd core dump.
it is pf_overload_task as you can see on the capture.

In fact, in the pf.c the pf_overload_tack not initialize,suddenly the pf_status falls on a NULL value VNET.
Seen by swi6_task_queue the td_vnet is not properly initialize

I have go a screenshot if you want.
>How-To-Repeat:
Compile a freebsd kernel 10-CURRENT with option VIMAGES
In pf.conf add a new rules with overload.
