Changing type since the crash was fixed under issue23919.

There remains (possibly) the failure of 
test_sendfile_close_peer_in_the_middle_of_receiving.

Karthikeyan Singaravelan  added the comment:

ProactorEventLoop is the default event loop with issue34687. There doesn't seem 
to be any warnings in buildbots as I have checked and as @panesen has mentioned 
this is not consistent. I am adding Victor as a notification if he has any 
thoughts. Victor, feel free to remove yourself if this is not relevant.

Thanks

Regarding the MVSC runtime message, there is an issue already here:

[issue34262] Asyncio test fails under Win 7

[Wöllert]

New submission from Wöllert :

When running tests I encounter the following error for the test:

test_sock_sendfile_not_regular_file 
(test.test_asyncio.test_proactor_events.ProactorEventLoopUnixSockSendfileTests)

---
Microsoft Visual C++ Runtime Library
---
Debug Assertion Failed!

Program: ...\EP2018\cpython\PCbuild\win32\python_d.exe
File: minkernel\crts\ucrt\src\appcrt\lowio\osfinfo.cpp
Line: 257

Expression: fh >= 0 && (unsigned)fh < (unsigned)_nhandle


---

However, when ignoring the MSCR error, the tests succeed without failing.

In addition the following failed (but not consistently):

==
FAIL: test_sendfile_close_peer_in_the_middle_of_receiving 
(test.test_asyncio.test_events.ProactorEventLoopTests)
