terminate called after throwing an instance of 'std::length_error'

Aborted (core dumped) example code:
note that this needs quite some ram (run on 128GB)
import pyarrow as pa
ids = [x for x in range(2**24)]
text = ['a'*2**10]*2**24
schema = pa.schema([
('Id', pa.int32()),
('Text', pa.large_string()),
])
tab1 = pa.Table.from_arrays([ids, text],schema=schema)
tab2 = pa.Table.from_arrays([ids, text],schema=schema)
joined = tab1.join(tab2, keys='Id', right_keys='Id', left_suffix='tab1') the same results in a segfault, if i use this schema
schema = pa.schema([
('Id', pa.int32()),
('Text', pa.string()),
])
