> TestZStandardCompressorDecompressor fails a couple of tests on my machine with the latest zstd library (1.3.5).  Compression can fail to successfully finalize the stream when a small output buffer is used resulting in a failed to init error, and decompression with a direct buffer can fail with an invalid src size error.
