Create a config file with FQDN of nameservers as masters in auth-zone section. Current version of default unbound.config suits this condition.
Start unbound with `unbound -d` command and terminate it in short period of time. You should see a segfault.

It's fixed in upstream:

Comment 2 aegorenk 2020-04-16 12:24:39 UTC

There is error in previous comment.
Current version of default unbound.config should be modified to reproduce.

The following line:
master: 199.9.14.201         # b.root-servers.net

Should be replaced with:
master: b.root-servers.net
