The port of lua to OpenZFS modified lua to use int64_t for numbers instead of double. As part of this, a function for calculating exponentiation was replaced with a bit shift. Unfortunately, it did not handle negative values. Also, it only supported exponents numbers with 7 digits before before overflow. This supports exponents up to 15 digits before overflow. Clang's static analyzer reported this as "Result of operation is garbage or undefined" because the exponent was negative.
