Assuming this is indeed the same issue (which is not easy to verify on the spot because the link you posted does not mention a specific ICE it's trying to fix, nor does it reference a PR where the problem is shown in more detail), the patches handle the issue in different ways: - handle the case that there's an edge with uninitialized probability - initialize probability on some edges At first glance I'd say that one doesn't necessarily exclude the other.
