In general, adding or removing an override is not a breaking change.
Finalize works by chaining to the parent using base.Finalize. calling a
method on base will always say call <my direct parent>.Method. In the
JIT we would in the debug build see: "my direct parent" has the finalize
method so call that, but in the non-debug build see "my direct parent"
doesn't have a finalizer, so lets try one in the parent of that class.
Sadly, due to some limitations in System.Reflection, MCS does not
implement this correctly.
As you can tell, thats a pretty old bug ;-(
