> Another issue is that the GC doesn't prevent the crash. Would it be possible to prevent the crash without changing the behavior (ex: still call weakref callbacks)?
I discussed with Pablo and it doesn't seem possible to prevent to clear a function if it is indirectly used as a callback for a weak reference to a object which doesn't implement tp_traverse properly (like the CFFI type).
The best that we can do is to detect the bug in C extension and emit a warning explaining the bug and suggesting a way to fix it. |
