Daniel Nugent created ARROW-8105:
------------------------------------
Summary: [Python] pyarrow.array segfaults when passed masked array
with shrunken mask
Key: ARROW-8105
URL: https://issues.apache.org/jira/browse/ARROW-8105
Project: Apache Arrow
Issue Type: Bug
Reporter: Daniel Nugent
{code:python}
>>> import numpy as np, pyarrow as pa
>>> pa.array(np.ma.array([0]))
{code}
I *think* the issue might be here because when the masked array has a shrunken
mask, it's values is False rather than the boolean mask array.
{code:python}
if isinstance(values, np.ma.MaskedArray):
if mask is not None:
raise ValueError("Cannot pass a numpy masked array and "
"specify a mask at the same time")
else:
mask = values.mask
values = values.data
{code}
