================
Comment at: llvm/lib/Transforms/Scalar/Reassociate.cpp:835
       // expression tree should be the same even after reassociation).
-      replaceDbgUsesWithUndef(ExpressionChanged);
+      replaceDbgUsesWithUndef(ExpressionChangedStart);
 
----------------
As a side note, I don't think we need to do this bit either for unchanged expressions.
