This is a known bug in 20.8.0, fixed in 20.11.0

Are you sure this is the core that was dumped above?  I would expect
to see a pkgin core.

I'm almost certain it wouldn't, certainly the only place it does run
(actions.c, do_pkg_install()), you would expect to see some further
output beforehand, which doesn't match your output.

If this really is a pkg_add.core from a pkgin segfault, then I think
the only thing that would explain this is a really bad build that is
completely re-arranging some of the code.
