On the machine where you do development work, and have to deal with

Permanently go back to the "old" way:
cat 'kernel.core_pattern = core' >> /etc/sysctl.conf
Also, I can't tell if it is still screwed up or not because
the bugzilla about it is incomprehensible, but you may
also need to edit /etc/systemd/system.conf and set
DefaultLimitCORE=0:infinity
At one time, this changed so that ulimit was always set for
everyone to always dump core (in the previous reality
you had to use ulimit -c to enable core dumps when you
knew you wanted them). This changed default then left core
files scattered all over your system.
