sudo bash
pkg install -y kyua
kyua test /usr/tests/local/atf/atf-c++/build_test

As far as core dumps? Yeah.. I can post one tomorrow (I’m testing out some things right now and I’d rather not interrupt it). Key piece is that if I use the package from pkg.FreeBSD.org it cores, but if I build it myself from ports, everything’s fine and dandy.

Thanks!
