With this, test-country only reports an extra:
   libloc: loc_new: ctx 05021298 created

But with '-DENABLE_DEBUG' there's way too much trace
to be useful.

An issue with OpenSSL and 'loc_database_verify()'?

Yes, but 'test-signature' works fine. It's just when calling
'EVP_VerifyXX()' functions from a .dll (like a Python module), it
fails with 'no OPENSSL_AppLink".

With your URL above,
  set loc_log=7 & py -3 location.py --database location-2020-10-16.db verify:

libloc: loc_new: ctx 0FDACEE8 created

BUT, with 'location-2020-05-15.db', there is this error:

Check yourself if the 'location-2020-05-15.db.xz' is still in the archive.
