Indeed, and I think this is our culprit.

With Solaris 10 11/06 (aka update 3), Solaris Trusted Extensions were 
introduced, and this added a new member (cr_label) to the cred_t struct.

I'm guessing that we're stomping around inside cred_t when storing the 
PAG there (right?) and the new member is throwing everything off.
