Segmentation fault

### Describe the bug

Using various version for datasets, I'm no more longer able to load that dataset without a segmentation fault. 
Several others files are also concerned. 

### Steps to reproduce the bug

# Create a new venv 
python3 -m venv venv_test 
source venv_test/bin/activate

# Install the latest version 
pip install datasets

# Load that dataset
python3 -q -X faulthandler -c "from datasets import load_dataset;  load_dataset('EuropeanParliament/Eurovoc', '1998-09')"

### Expected behavior

Data must be loaded 

### Environment info

datasets==2.19.0
Python 3.11.7
Darwin  22.5.0 Darwin Kernel Version 22.5.0: Mon Apr 24 20:51:50 PDT 2023; root:xnu-8796.121.2~5/RELEASE_X86_64 x86_64

Comments:
I downloaded the jsonl file and extract it manually. 
The issue seems to be related to pyarrow.json 



python3 -q -X faulthandler -c "from datasets import load_dataset;  load_dataset('json', data_files='/Users/scampion/Downloads/1998-09.jsonl')"
