[New-bugs-announce] [issue41229] Asynchronous generator memory leak

[JIanqiu Tao]

New submission from JIanqiu Tao <zkonge at outlook.com>:

The resource used by asynchronous generator can't be released properly when works with "asend" method.

Besides, in Python 3.7-, a RuntimeError was raised when asyncio.run complete, but the message is puzzling:
  RuntimeError: can't send non-None value to a just-started coroutine

In Python 3.8+, No Exception showed.

Python3.5 unsupport yield in async function, so it seems no affect?
