Thanks for reporting this. I don't understand how it could fail at that
point. Could you rerun the failing test and see what the values of
key, *key, key->cert and *key->cert are? It's possible to run just the
sshkey unit test using:
./regress/unittests/sshkey/test_sshkey -d regress/unittests/sshkey/testdata
from the top-level directory.
