This issue is related to bpo-36389 "Add gc.enable_object_debugger(): detect corrupted Python objects in the GC. I propose to call _PyObject_IsFreed() in visit_decref() in debug mode, to get a better error message if something goes wrong. visit_decref() is commonly found in C traceback (ex: gdb backtrace) of bugs related to the garbage collector.
