24 **Example Frame**: see zstd/tests/golden-decompression/zeroSeq_2B.zst
26 The zstd decoder incorrectly expects FSE tables when there are 0 sequences present in the block
27 if the value 0 is encoded using the 2-bytes format.
31 because representing 0 sequences with the 2-bytes format is inefficient
