Segfaults when importing python-libsbml with python3.11 and `-Werror`

[dweindl]

Importing the current manylinux Python 3.11 wheel (python_libsbml-5.20.5-cp311-cp311-manylinux_2_17_x86_64.manylinux2014_x86_64.whl) with Python 3.11.11 on Ubuntu with -Werror (common under pytest) results in a segfault.

After creating a new virtual environment with Python 3.11 and installing python-libsbml from PyPI:

# works
$ python -c "import libsbml"

$ python -Werror -c "import libsbml"
Fatal Python error: Segmentation fault

This is a known problem with swig4.3 (swig/swig#3061, swig/swig#2881).

Here a workaround I used elsewhere: https://github.com/AMICI-dev/AMICI/blob/2753e10242fb2393ead4d0bddfd44bdc5e9ef27f/python/sdist/amici/__init__.py#L106-L116. (I.e., catching the warnings shown above with -Wall when importing the extension module.)

EDIT: This also affects Python 3.10, but not Python 3.12 and 3.13.
