This is a known bug in 2.0.3 when it is built with
-UPCMK_TIME_EMERGENCY_CGT in the C flags, which is not the default.
Fedora 31 and an Ubuntu release are known to have used that option (bug
reports are open for both distributions, and hopefully updated packages
will be available before long).
The only fix is to use a different pacemaker version on those
platforms.
