_PyGen_Finalize() should not fail with an exception.  Doing so can cause various SystemErrors or even fatal errors.  For example, run this with "python -Werror":

    import gc
    async def f():
    gc.collect()   # RuntimeWarning, but with -Werror

Patch attached.  Test missing (turn the above example in a test; also I didn't re-run all tests with this patch).

You're welcome.  Unrelated, but I'm collecting similar issues in a file at .  After reporting the first two, I stopped, and will report them all in bulk some time later, but you may be interested in fixing a couple more for the upcoming 3.6 release.
