burnpanck opened a new issue, #45880:
URL: https://github.com/apache/arrow/issues/45880
### Describe the bug, including details regarding any error messages,
version, and platform.
The following code fails for me with the interpreter crashing:
```python
import pyarrow as pa
print(pa.__version__)
a = pa.array([dict(a=1,b=2),dict(c=3)],pa.map_(pa.utf8(), pa.uint16()))
print(a.value_parent_indices()) # <-- crashes
```
The very similar `ListArray` implementation does not seem to have this
problem
```python
import pyarrow as pa
print(pa.__version__)
a = pa.array(
[list(d.items()) for d in [dict(a=1,b=2),dict(c=3)]],
pa.list_(pa.struct([pa.field("key",pa.utf8()),
pa.field("value",pa.uint16())])),
)
print(a.value_parent_indices())
```
