   Hmm so I found the "error". If I use exactly the schema from the read batch, 
it works (no segfaults, no garbled output).
   But if I print the schema:
   ```
   smiles: string
   id: string
   ```
   
   So, what is different from manually specifying the schema like I did in the 
beginning?
   
   ```
   schema = pa.schema([
       ('smiles', pa.string()),
       ('id', pa.string())
   ])
   ```
