That sounds like a bug, probably adjustCopiesBackFrom needs to check ACopyMI->isFullCopy(). Do you have a test case for this? Yes and No. Yes because the example is from a unit testcase that I have. No because it manifests itself only with my half baked pass that I was talking about earlier in this thread.
