Below is the backtrace from the Ruby test case you provided. It shows that it fails in SWIG related code. The attached patch was recently applied in version 3.7-3.1 to build with SWIG 4.3 and close the above bug. The patch is needed to match the latest SWIG so reverting that patch is not an option - the code in question can't compile without it. I think that the root cause of this is SWIG. Is there anyone who has had previous experience of Ruby and SWIG who can help with this?

From 8e0e718bae53fff30831b92cd784151d475a20da Mon Sep 17 00:00:00 2001 From: Petr Lautrbach <lautrb...@redhat.com> Date: Wed, 16 Oct 2024 20:48:11 +0200 Subject: [PATCH] libselinux: fix swig bindings for 4.3.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit https://github.com/swig/swig/blob/master/CHANGES.current "[Python] #2907 Fix returning null from functions with output parameters. Ensures OUTPUT and INOUT typemaps are handled consistently wrt return type. New declaration of SWIG_Python_AppendOutput is now: SWIG_Python_AppendOutput(PyObject* result, PyObject* obj, int is_void); The 3rd parameter is new and the new $isvoid special variable should be passed to it, indicating whether or not the wrapped function returns void. Also consider replacing with: SWIG_AppendOutput(PyObject* result, PyObject* obj); which calls SWIG_Python_AppendOutput with same parameters but adding $isvoid for final parameter."
