segfaults when passing it a chunked array
Joris Van den Bossche created ARROW-9920:
--------------------------------------------
Summary: [Python] pyarrow.concat_arrays segfaults when passing it a chunked array
Key: ARROW-9920
URL: https://issues.apache.org/jira/browse/ARROW-9920
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Joris Van den Bossche
One can concat the chunks of a ChunkedArray with {{concat_arrays}} passing it the list of chunks:
{code}
In [1]: arr = pa.chunked_array([[0, 1], [3, 4]])
In [2]: pa.concat_arrays(arr.chunks)
Out[2]:
<pyarrow.lib.Int64Array object at 0x7ff88fc76408>
[
0,
1,
3,
4
]
{code}
but if passing the chunked array itself, you get a segfault:
{code}
In [4]: pa.concat_arrays(arr)
Segmentation fault (core dumped)
{code}
