    Avoid a crash when attempting to change password
    
    In some cases we could keep stack garbage in a local pointer
    variable until the cleanup at the end of the function wherein
    krb5_free_context() would choke on the invalid non-NULL value.
    Initialize to zero to avoid the issue (should be written as NULL
    but stick to the prevailing style).
