> Hi !
> If you create a StructArray with an ExtensionArray in it, then both to_numpy
> and to_pandas segfault in python:
> {code:java}
> import pyarrow as pa
> class CustomType(pa.PyExtensionType):
> def __init__(self):
> pa.PyExtensionType.__init__(self, pa.binary())
> def __reduce__(self):
> return CustomType, ()
> arr = pa.ExtensionArray.from_storage(CustomType(), pa.array([b"foo"]))
> pa.StructArray.from_arrays([arr], ["name"]).to_numpy(zero_copy_only=False)
> {code}
> Thanks in advance for the help !
