Hmm, it looks like in 3.7+, _PyRuntime is marked PyAPI_DATA, which I think should make it exported from dynsym? https://github.com/python/cpython/blob/4b430e5f6954ef4b248e95bfb4087635dcdefc6d/Include/internal/pystate.h#L206 And PyInterpreterState_Head is just _PyRuntime.interpreters.head. So maybe this is already done... -n -- Nathaniel J.
