Hello,
I'm tryint to upgrade a bhyve guest from stable/11 to stable/12.
pkg(8) for example crashes with signal 11.
I looked for other binaries affected by
ldd /usr/sbin/* | & grep 'signal 11$'
wich gives
/usr/sbin/auditdistd: signal 11
/usr/sbin/bhyve: signal 11
/usr/sbin/bsnmpd: signal
/usr/sbin/gssd: signal 11
/usr/sbin/hostapd: signal 11
/usr/sbin/iprop-log: signal 11
/usr/sbin/keyserv: signal 11
/usr/sbin/kstash: signal 11
/usr/sbin/ktutil: signal 11
/usr/sbin/local-unbound: signal 11
/usr/sbin/local-unbound-anchor: signal 11
/usr/sbin/local-unbound-checkconf: signal 11
/usr/sbin/local-unbound-control: signal 11
/usr/sbin/ntp-keygen: signal 11
/usr/sbin/ntpd: signal 11
/usr/sbin/ntpdate: signal 11
/usr/sbin/ntpdc: signal 11
/usr/sbin/pkg: signal 11
/usr/sbin/ppp: signal 11
/usr/sbin/sntp: signal 11
/usr/sbin/sshd: signal 11
/usr/sbin/tcpdump: signal 11
/usr/sbin/uefisign: signal 11
/usr/sbin/wpa_supplicant: signal 11
They all seem to have in common beeing linked against
'/lib/libcrypto.so.111'

I have no idea how to analyze further or what the reason could be (like
mentioned, all binaries listed dump core after opening lib/libcrypto.so.111
gdb shows:
Core was generated by `/usr/sbin/auditdistd'.

Any help highly appreciated.
This is with a live CD (amd64), compiled with stable/12 from today (so
clang 7.01).
The bhyve guest has 2GB hardwired and ran stable/11 beforehand, which
compiled the live CD.
bhyve host is 11.2. But that shouldn't play a role, does it?
