---------------------------------------------

             Summary: [Python] Not providing a sort_key in the "select_k_unstable" kernel crashes
                 Key: ARROW-14003
                 URL: https://issues.apache.org/jira/browse/ARROW-14003
             Project: Apache Arrow

          Components: Python
            Reporter: Joris Van den Bossche

The new kernel added in ARROW-1565 crashes in Python if you don't specify a sort_key:

{code}
In [1]: import pyarrow.compute as pc

In [2]: arr = pa.array([1, 2, 3, 4])

In [3]: pc.select_k_unstable(arr, k=2)
Segmentation fault (core dumped)
{code}
