================
Comment at: lib/Transforms/Scalar/LoopUnswitch.cpp:1374
+        BI->eraseFromParent();
+        Worklist.push_back(NBI);
+      }
----------------
See the comment near the beginning of LoopUnswitch::TryTrivialLoopUnswitch for a description of all the state you aren't updating correctly.

Also, I think you meant "isa<ConstantInt>(BI->getCondition())".
