Stefan Behnel: > Making _PyGC_FINALIZED() internal broke Cython (https://github.com/cython/cython/issues/2721). It's used in the finaliser implementation (https://github.com/cython/cython/blob/da657c8e326a419cde8ae6ea91be9661b9622504/Cython/Compiler/ModuleNode.py#L1442-L1456), to determine if an object for which tp_dealloc() is called has already been finalised or whether we have to do it. I'm not sure how to deal with this on our side now. Any clue? I wrote PR 10626 to add _PyGC_FINALIZED() back to the C API. My intent was only to remove _PyObject_GC_TRACK(o) and _PyObject_GC_UNTRACK(o) from the public C API. I didn't expect that anyone would use _PyGC_FINALIZED() :-)
