It is just defined such that two independently derived access values may or may not be equal. This is very similar to the way floating point works; it shouldn't be that surprising. That is: A := F'Access; B := A; C := G'Access; D := C; E := F'Acesss; if A = B then -- Must be true. if C = D then -- Must be true. if A = C then -- Must be false. if B = D then -- Must be false. if A = E then -- May be either true or false. if B = E then -- May be either true or false.
