Describe the bug
I followed the contributing code guidelines and ran into a segmentation fault when running the test sklearn/tests/test_common.py. It appears to come from libsvm.fit(...).
I am not sure whether it is a problem related to my device or not.
Steps/Code to Reproduce
git clone https://github.com/scikit-learn/scikit-learn.git
cd scikit-learn
python3 -m venv venv
source venv/bin/activate
pip install pip --upgrade
pip install numpy scipy matplotlib pytest sphinx cython ipykernel
pip install --no-build-isolation --editable .
pytest sklearn/tests/test_common.pyExpected Results
No error is thrown.
Actual Results
Fatal Python error: Segmentation fault
