Cannot figure out how to open and view a coredump

I've been having frequent issues on not just Linux but also Windows, where the symptoms are always the same: all the applications notify me that they crash, and for Linux, the screen freezes, while on Windows there's a blue screen in addition. Trying to analyze Windows' dump of course proved futile. However, while I did get a core dump on Linux in /var/lib/systemd/coredumps, the file within the xz archive, when opened with a log viewer like KSystemLog, shows timestamps but also binary code in the description field. The `coredumpctl` utility is little help to me too. Not even a Google search on "systemd core dump view" gave any good results, seeming to discard the keyword `view` from the query.

So my question is: how do I view a core dump or get coredumpctl to analyze it? `coredumpctl gdb` returns nothing

Re: Cannot figure out how to open and view a coredump

$ coredumpctl gdb <keyword>
e.g.
$ coredumpctl gdb vlc
will show the latest vlc dump file with gdb.
