Description

Sorting a non-chunked array has some sort of reference problem. Some operations on the resulting indices array crash.

import pyarrow as pa, pyarrow.compute as pc

array = pa.array(list("abcba"))
assert pc.sort_indices(pa.chunked_array([array])).take([0])
assert pc.array_sort_indices(pa.chunked_array([array])).take([0])
pc.sort_indices(array).take([0])  # crash
pc.array_sort_indices(array).take([0])  # crash
