    Description

      I'm not sure what the expected behaviour should be, but it's not segfaulting!

      import pandas as pd
      import pyarrow as pa
      print("Pandas: %s" % pd.__version__)
      print("Pyarrow: %s" % pa.__version__)
      df = pd.DataFrame({"B": (1, 'A')})
      df = df.assign(B=df.B.astype("category"))
      pa.Table.from_pandas(df)  # this segfaults!
      

      Versions:

      Pandas: 0.20.1
      Pyarrow: 0.5.0
