[issue42538] AsyncIO strange behaviour

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

I understand the issue as the following:

1. You don't save the result of `asyncio.create_task()` somewhere.
The task object is dereferenced and thus you see a warning.

2. With PYTHONASYNCIODEBUG on the task is referenced also by internal debug structure, that's why you don't see the warning.

Perhaps we should store a weak reference to task in _source_traceback

Minor thing but nice to have it fixed.
