> 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}
