The zstd format specification doesn't enforce that Huffman compressed literals (including the table) have to be smaller than the uncompressed literals. The compressor will never Huffman compress literals if the compressed size is larger than the uncompressed size. The decompresser doesn't accept Huffman compressed literals with 4 streams whose compressed size is at least as large as the uncompressed size. * Make the decompresser accept Huffman compressed literals whose size increases. * Add a test case that exposes the bug. The compressed file has to be statically generated, since the compressor won't normally produce files that expose the bug. |
