The problem was that parts of Simd8x16ShuffleOperand were uninitialized. Original message: [wasm] Stop decoding operands after error. When we decode operands of WebAssembly instructions, we do not use the current pc but a pc of the instruction plus some offset. However, the pc of the instruction + offset can become invalid in case of a decoder error. Therefore we have to stop decoding operands explicitly in case of an error.
