> Key: ARROW-4774
> URL: https://issues.apache.org/jira/browse/ARROW-4774
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.11.1, 0.12.1
> Environment: Windows 10 16299.431, Python 3.6.4 64-bit, pyarrow 0.11.1

> When writing a table to a parquet file that contains both flat arrays and
> nested array data it causes the Python to crash
> Reproducer:
> {code:python}
> import pyarrow as pa
> import pyarrow.parquet as pq
> import numpy as np
> array1 = np.array([0, 1, 2], dtype=np.uint8)
> array2 = np.array([[0,1,2], [3, 4, 5]], dtype=np.uint8).T
> t1 = pa.uint8()
> t2 = pa.list_(pa.uint8())
> fields = [
> pa.field('a1', t1),
> pa.field('a2', t2)
> ]
> myschema = pa.schema(fields)
> mytable = pa.Table.from_arrays([
> pa.array(array1, type=t1),
> pa.array([array2[:,0], array2[:,1]], type=t2)],
> schema=myschema)
> pq.write_table(mytable, 'example.parquet')
> {code}
> Windows 10 (Python 3.6.4 64-bit, pyarrow 0.11.1) crash code:
> {code:bash}
> Process finished with exit code -1073741819 (0xC0000005)
> {code}
