--- Comment #14 from vova@fbsd.ru ---
Looking at my panic above:

looks like fr 5 was in stack was broken 

backtrace shows:
#5  0xffffffff834e666a in ipfwlog_clone_create (ifc=<optimized out>, unit=0,
params=<optimized out>) at /usr/src/sys/netpfil/ipfw/ip_fw_bpf.c:134

in fact, it should be 
ipfw_check_packet

and according to panic - it was ipfw_check_packet() at
https://github.com/freebsd/freebsd-src/blob/087fc6ae0a8c/sys/netpfil/ipfw/ip_fw_pfil.c#L153

but in dump - this frame was overriten with bad data somehow
