subject: yarrow code does not initialize keyblock enctype and uses unitialized value
ticket: 6625
tags: pullup
The yarrow code uses a keyblock that is partially initialized. This results
in krb5_k_free_key trying to look up the enctype to call the free handler.
One of the valgrind reports: (there are several paths)
