      Description

      Repro code.

      Seems that unexpected deallocation occured.

      import pandas as pd
      import pyarrow as pa
      
      df = pd.DataFrame({
      'Foo': ['A', 'A', 'B', 'B']
      })
      
      table = pa.Table.from_pandas(df)
      
      df = table.to_pandas(strings_to_categorical=True)
