Nils - It's always possible, but I don't see any obvious culprits in my path. OTOH, I do see is that readme calls for "GCC versions from 8.4.0 to 13.x" whereas I'm running gcc 14.3.0. (Has anyone else tested gcc 14.x?) I also see that readme calls for python3 versions "3.9.x to 3.12.x" whereas I'm running python3 3.6.15, which induces a build of python by the build script. Since the symbol in question is in a cpython .so file, the bug may have to do with sage's building of python3-3.12.5 in "~/sage-10.7/local/var/lib/sage/venv-python3.12.5". (Has anyone else tested with the script-built python3-3.12.5?)
