 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.
