Not exactly, no. What e.g. property-4 checks is that an object with baseline+v2
and an object with v2+v4 correctly combine to baseline+v2+v4. Them combining to
baseline+v2+v3+v4 is something that should fail the test.

And yes, such a test very likely should not involved system supplied objects
and as a result likely shouldn't use the C compiler to drive the linking.
