+More modern systems facilitate [`systemd-coredump`](https://www.freedesktop.org/software/systemd/man/systemd-coredump.html) (via a similar named package) to controll coredumps.
+On most systems it will put compressed coredumps to `/var/lib/systemd/coredump`. 
+
+In order to use automatic coredump analysis with the unittests you need to configure
