It turns out gss_add_cred() really needed a complete rewrite. It's much better to first have a gss_duplicate_cred() (which has been needed for other reasons anyways), and use that when the input_cred_handle is not GSS_C_NO_CREDENTIAL and output_cred_handle is not NULL, then mutate that duplicate credential handle (or the input_cred_handle if output_cred_handle is NULL).
