Tried reproducing with

options KDB
options DDB
options KDB_UNATTENDED
options WITNESS
options WITNESS_SKIPSPIN
options INVARIANTS
options INVARIANT_SUPPORT

and without FLOWTABLE.

Instead of fatal trap 12 I get trap 9, general protection fault now
(same for the three attempts I made), and the vmcore file seems unusable:=


remilia@gw ~ % sudo kgdb /usr/obj/usr/src/sys/Eientei/kernel.debug
/var/crash/vmcore.1
(skip)
This GDB was configured as "amd64-marcel-freebsd"...
Cannot access memory at address 0xfff08de9ff6d62dc
(kgdb) bt
#0  0x0000000000000000 in ?? ()
Cannot access memory at address 0x0

Can someone suggest a way to properly debug this?
