New submission from STINNER Victor <vstin...@python.org>:
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))
