-------------------------------------
Yes, that was basically my thinking except to handle a Schema passed to
{{names=}} as though it were passed as {{schema=}}

> I'm not sure if this should be reported to Parquet or here.
> When I tried to serialize a pyarrow table with a fixed size binary field
> (holds 16 byte UUID4 information) to a parquet file, segmentation fault
> occurs.
> Here is the minimal example to reproduce:
> {{import pyarrow as pa}}
> {{from pyarrow import parquet as pq}}
> {{data = \{"col": pa.array([b"1234" for _ in range(10)])}}}
> {{fields = [("col", pa.binary(4))]}}
> {{schema = pa.schema(fields)}}
> {{table = pa.table(data, schema)}}
> {{pq.write_table(table, "test.parquet")}}
> {{segmentation fault (core dumped) ipython}}
>
> Yet, it works if I don't specify the size of the binary field.
> {{import pyarrow as pa}}
> {{from pyarrow import parquet as pq}}
> {{data = \{"col": pa.array([b"1234" for _ in range(10)])}}}
> {{fields = [("col", pa.binary())]}}
> {{schema = pa.schema(fields)}}
> {{table = pa.table(data, schema)}}
> {{pq.write_table(table, "test.parquet")}}
> Thanks,
