[Python] Python Oracledb - Segmentation Fault Error

When I use oracledb Python module in Thick mode, I get a Segmentation fault error on a huge database request with Oracle v11.2 client.

Code:

# main.py
import oracledb

oracledb.init_oracle(lib_dir='path/to/lib', config_dir='path/to/config')
connection = oracledb.connect(user='user', password='pwd', dsn=cs, sid=sid, encoding='utf-8')
cursor = connection.cursor()
cur.arraysize = 100

results = cur.execute('SELECT * FROM MY_TABLE')


Error:

python main.py
Segmentation fault


What is the problem with this request?
