All ISC programs dumping core after update to netbsd-10 stable

I have an apu2 running NetBSD 10 that has been very stable.

I updated it from uilds that I did

I do this all the time, on many machines.   A domU that I did it on is
also showing this problem.  I did update BIOS on the apu2, but I rolled
that back, and the domU is on different hardware.


I rolled back the kernel, and am working on libs, but it seems something
has gone wrong.

I am seeing crashes from named, dhcpd, dig, rndc, nsupdate.  Everything
else is fine.

pointers appreciated, and I wonder if anyone else is seeing something.
