jrmccluskey opened a new issue, #22939: URL: https://github.com/apache/beam/issues/22939
### What happened? [test_concatenated_compressed_file() in filesystem_test.py](https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/filesystem_test.py#L489) violates an assert statement in [zstandard's decompressionobj.c function](https://github.com/indygreg/python-zstandard/blob/0.18.0/c-ext/decompressobj.c#L98) and can fail if using a version of zstandard compiled without the NDEBUG flag. This demonstrates that the usage of zstandard is performing behavior that the library itself considers impossible and points towards potential issues. ### Issue Priority Priority: 2 ### Issue Component Component: test-failures -- This is an automated message from the Apache Git Service.
