I've pushed an update to fix the builds, add some assertions and to add the `gdwarf-4` GCC flag for now to exclude DWARF 5 and let the tests pass again (@erikj79 is that the right place? Do I need to add it at other places as well?). 

I think this `gdwarf-4` flag is currently the only option to eventually move forward with this RFE without extending the parser to support DWARF 5. I could still do that as a follow-up task and then remove the `gdwarf-4` flag again. But also adding DWARF 5 support in this patch is probably too much. What do you think about that?

As mentioned above, I'm going to be away for the rest of the month. I will get back to this PR at the start of May again.

Cheers,
Christian
