You have to set ``LimitCORE=unlimited'' (or similar value).
Tested it with ``pkill -11 bird'' and got a coredump:

TIME                           PID UID GID SIG     COREFILE EXE             SIZE

The config I'm currently using is: (I only changed the '-R' and added the LimitCORE for this test here)
