commit 551e88e76e537e45f6c80eadaefeb790994f83f9

    Initialize some data structure magic fields
    
    Static analyzers may complain if they see a data structure copied with
    an uninitialized field, even if the copy target won't use the field.
    Add magic field initializers in three such places.
