Fantastic question! I have a repro IR here https://gist.github.com/raikonenfnu/5f9df8748712fada5b167abd696a13fa. However, it is failing not from an IR level, but rather it fails during a lowering, because it calls into `createOrFold` here https://github.com/llvm/torch-mlir/blob/80a3dfddd341c72ab9bd6c6688b872bf3a5e4ddb/lib/Conversion/TorchToLinalg/Pooling.cpp#L918-L921

so not so sure if I can recreate that in IR 😅
