Fix a bug where, in the case the memory was tainted before calling the
slicemethod with a desired length of0, the returned bytes array, instead of being a zero-length slice was an array of arbitrary length based on the values that previously populated that memory region.Overall, the usage of zero-length slices should be pretty unusual and so, hopefully this bug does not have far-reaching implications. Nonetheless, please update the library to the new version ASAP if you're using it in production.
