Yes, but if krb5_prompter_posix() had been designed to allocate the
memory, the caller would probably free it with krb5_free_data() (or
krb5_free_data_contents(), perhaps), so the actual free would happen
inside the library.

I chose not to complicate my message with that detail, but only
succeeded in adding three more messages to the thread. :)
