Krisztian Szucs commented on ARROW-2391:
----------------------------------------
Confirmed, it segfaults with the latest master.
> [Python] Segmentation fault from PyArrow when mapping Pandas datetime column
> to pyarrow.date64
> ----------------------------------------------------------------------------------------------
>
> Key: ARROW-2391
> URL: https://issues.apache.org/jira/browse/ARROW-2391
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.9.0
> Environment: Mac OS High Sierra
> Python 3.6
> Reporter: Dave Challis
> Priority: Major
>
> When trying to call `pyarrow.Table.from_pandas` with a `pandas.DataFrame` and
> a `pyarrow.Schema` provided, the function call results in a segmentation
> fault if Pandas `datetime64[ns]` column tries to be converted to a
> `pyarrow.date64` type.
> A minimal example which shows this is:
> {code:python}
> import pandas as pd
> import pyarrow as pa
> df = pd.DataFrame({'created': ['2018-05-10T10:24:01']})
> df['created'] = pd.to_datetime(df['created'])}}
> schema = pa.schema([pa.field('created', pa.date64())])
> pa.Table.from_pandas(df, schema=schema)
> {code}
> Executing the above causes the python interpreter to exit with "Segmentation
> fault: 11".
> Attempting to convert into various other datatypes (by specifying different
> schemas) either succeeds, or raises an exception if the conversion is invalid.
