Using the backtrace from gdb I was able to find the culprit: the
openldap-client. :-(

While the updated freeRADIUS server was compiled against openssl 1.1.1d
from the FreeBSD ports tree, the openldap-client was compiled against
openssl 1.0.2s from the base system. This led to the segmentation violation.

Once I re-installed openldap-client compiled against openssl 1.1.1d from the
ports tree radiusd started just fine.

On the previous system openldap-client and freeradius were compiled against a
mix of openssl libraries from base and ports, too - but both openssl libraries
were the same version ... so it did not matter.

Thanks for your help!
Regards
Ferdinand
