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)
