 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)
