Has anyone experienced Abort trap: 6 when executing rcs commands?

Environment: BSD on macOS 10.13.6 - newly upgraded

After the upgrade, any rcs command (ci, rlog for example) returns =
=E2=80=9CAbort trap: 6=E2=80=9D and only that.

Has anyone encountered this on an upgrade?  Does anyone have a solution?

Thanks in advance,
Philip
