This is 360 CodeSafe Team, we found a unused value in zopfli. See https://github.com/google/zopfli/blob/ae43a8b73827577c4b19b005b6eed81f5cf9bbac/src/zopfli/deflate.c#L692, the value assigned to detect_block_size seeme unused and it will be overwrite at https://github.com/google/zopfli/blob/master/src/zopfli/deflate.c#L729.

Since I'm unfamiliar with zopfli, please forgive me if there is anything wrong with my description.
