Thanks for the report! The problem was that we did not record the recipe if a simplified VPValue is used. I pushed faebc6bf108e <https://reviews.llvm.org/rGfaebc6bf108eccdfd75917636c64137f73a7bda7> to fix it for now, but as Ayal pointed out, it might be worth the simplify the handling, which I'll look into separately.
