I haven't spent much time investigating this since this is GC and I know nothing about GC. For the first test for example the output on CoreRT is:

Expected exception not thrown!
Test failed!

On CoreCLR it is:

In Finalize() of Dummy
Expected exception
Test passed!

These tests fail because of we are using conservative GC reporting currently. The tests expect the objects to be collected, but some conservative root keeps them alive.
