To fix bpo-40170, I would like to modify Py_TRASHCAN_BEGIN() macro to use PyType_GetSlot() to get the deallocator function, rather than accessing directly the PyTypeObject.tp_dealloc member. The problem is that currently PyType_GetSlot() only works on heap allocated types.

Would it be possible to add support for statically allocated types to PyType_GetSlot()?

Py_TRASHCAN_BEGIN() is currently defined as:

#define Py_TRASHCAN_BEGIN(op, dealloc) \
    Py_TRASHCAN_BEGIN_CONDITION(op, \
        Py_TYPE(op)->tp_dealloc == (destructor)(dealloc))
