I've recreated it here with -ud. Will debug.

[bdrewery]

A workaround is pkg upgrade -Fy

Hm good to know, at last for all my DMZ systems. As bonus it seems the command explains more what will happen during the upgrade and this can be logged remote e.g. via salt before the final upgrade.

[bdrewery]

pkg fetch -d <pkg already installed> has the same crash/trace:

pkg fetch -u is pulling in things that are not updated as well. Likely a separate issue.

[ohauer]

Hm, -u always pulled the pkg when the checksum has changed, so the fetched files in the cache where always consistent with the information in the $repo-site.sqlite database. This was a nice feature for short update times and In case someone has not a stable or slow access to the update servers or only limited time to fetch new / changed packages. I used it also to fetch all files to one remote system, sync /var/cache/pkg /var/db/repo-site.sqlite to all other systems on the remote site and then run pkg upgrade -U. Similar to the `yum --downloadonly' plugin on RHEL.
