based on report from lha@stacken.kth.se
"identP = (struct Identity *)malloc(1);

This can't be right, there should not be an assumption how the
c-compiler will lay out code. I find it acceptable to do something like this

           /* sizeof valid + offset of valid. */
           i.. = malloc(sizeof(identP->valid) + (int)&(((struct Identity *)0)->valid));

But then, why not just allocate a whole identP and be happy. A afsUUID
is not that bloted (16 bytes) so I can't see why way this is
chosen. 20 bytes will probably be allocated on 32 bit platforms for
the whole struct Identity."
