I currently don't know of any other optimisation phases where the debug information for the results of a phi node is incorrect;   but I would not be surprised to find that once the loop rotate issue is fixed and the information is able to correctly propagate in this phase that other optimisation phases which copy phi nodes are also found to have a problem.
