After https://github.com/python/cpython/pull/12946, there exists an issue on MacOS due to the two-level namespace for symbol resolution. If a C extension links against libpython.dylib, all symbols dependencies from the Python C API will be bound to libpython. When the C extension is loaded into a process launched by running the `python` binary, there will be two active copies of the python runtime. This can lead to crashes if objects from one runtime are used by the other.
