[New-bugs-announce] [issue24867] Asyncio get_frame fails with native coroutines

[David Griffin]

New submission from David Griffin:

I've been playing around with native coroutines and asyncio, and came across an issue with retrieving exceptions from tasks: The get_frame method on a Task in asyncio fails with an AttibuteError because it assumes that gi_frame as the attribute containing the stack frame; with native coroutines it's cr_frame.

I've attached a quick patch that just uses hasattr to see if gi_frame is present, and if not try cr_frame. This may not be the most elegant solution, but it does fix the issue. If there's any other stuff I can provide to help with this (within reason), just say the word.
