lesterfan opened a new issue, #47301: URL: https://github.com/apache/arrow/issues/47301
### Describe the bug, including details regarding any error messages, version, and platform. The following code currently seg faults on the main branch, where we create a fragment from a file-like object, which [is a supported operation](https://github.com/apache/arrow/blob/80addfab90b65c9127b46cc5c0ff48af4db1afb3/python/pyarrow/_dataset.pyx#L1364). ``` table = pa.table([ pa.array(['a', 'b', 'c']), pa.array([12, 11, 10]), pa.array(['dog', 'cat', 'rabbit']) ], names=['alpha', 'num', 'animal']) out = pa.BufferOutputStream() pq.write_table(table, out) buffer = out.getvalue() file_like = pa.BufferReader(buffer) parquet_format = ds.ParquetFileFormat() fragment = parquet_format.make_fragment(file_like) opened_file = fragment.open() ``` Note that other APIs such as `fragment.to_batches` do work as expected. ### Component(s) Python -- This is an automated message from the Apache Git Service.
