I'm sorry if this was already reported, but there's an overflow issue in concatenation of large arrays
In [1]: import pyarrow as pa
In [2]: str_array = pa.array(['a' * 128] * 10**8)
In [3]: large_array = pa.concat_arrays([str_array] * 50)
Segmentation fault (core dumped)
I suppose that this should be handled by upcast to large_string.
