What happens?

When trying to do a basic query in Python:

#! /usr/bin/python3
import duckdb

duckdb.read_csv('20503_switch_dump.csv')

it errors out with the following:

<jemalloc>: Out-of-range conf value: narenas:0

I am using the Python DuckDB client on Amazon Linux 2023. The Python version information is as follows:

Python 3.9.16 (main, Jul  5 2024, 00:00:00) 
[GCC 11.4.1 20230605 (Red Hat 11.4.1-2)] on linux

DuckDB was installed through pip3. I tried both the stable and nightly version (1.1.4.dev2005).

The duckdb CLI client (downloaded directly from the website) does work.

To Reproduce

• Create a fresh Amazon Linux 2023 EC2 t2.micro instance
• Install pip3: sudo yum install python3-pip
• Install Python DuckDB client: pip install duckdb
• Create test script test.py:

#! /usr/bin/python3
import duckdb

duckdb.read_csv('test.csv')

• Make script executable: chmod +x test.py
• Create test data test.csv:

a,b,c
1,2,3
4,5,6
7,8,9

• Running ./test.py gives <jemalloc>: Out-of-range conf value: narenas:0
