Tha´t s new to me.

You need to use the core dump to identify what line of code caused
the issue. If your machine is using systemd, there is an utility
(coredumpctl) that allows you to inspect it. There is a description
about how to do it at: 

https://wiki.archlinux.org/title/Core_dump

Once you check the source, I suggest you to take a look at the code
if it belongs to rasdaemon. If it came from some other place, e.g.
from one of rasdaemon dependencies, then you may need to open a bug
to the specific package on Ubuntu, if rasdaemon is passing the data
right to it.
