I think I have an idea why both versions are working. I would expect
that in the 'authdata' case gcc does not pass the krb5_authdata array
by value but by reference. In the '&authdata' case gcc passes the
pointer to the krb5_authdata array by value. As a result in both case
the same address is on the stack and krb5_encode_authdata_container()
can work as expected. I hope this makes sense.

Nevertheless I still think the 'authdata' version is the correct one.

bye,
Sumit
