[issue28471] Python 3.6b2 crashes with "Python memory allocator called without holding the GIL"

[Yury Selivanov]

New submission from Yury Selivanov:

The following Python program causes a segfault in Python 3.6b2:

    import socket
    import asyncio

    loop = asyncio.get_event_loop()


    sock = socket.socket()
    sock.close()

    async def client():
        reader, writer = await asyncio.open_connection(
            sock=sock,
            loop=loop)

    async def runner():
        await client()

    loop.run_until_complete(runner())
