Misleading exception stack

[kyuupichan]

• uvloop version: 0.9.1
• Python version: 3.6.4
• Platform: MacOSX
• Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Yes

Running the below with uvloop policy commented out results in an expected error:

ConnectionRefusedError: [Errno 61] Connect call failed ('127.0.0.1', 1)

Running with uvloop policy uncommented:

TypeError: getsockaddrarg() takes exactly 2 arguments (4 given)

This led me on a wild goose chase for a while...

import asyncio
import socket
import uvloop

def lss(address):
    loop = asyncio.get_event_loop()
    sock = socket.socket()
    sock.setblocking(False)
    coro = loop.sock_connect(sock, address)
    loop.run_until_complete(coro)

asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
lss(('localhost', 1))

IPv6 address?

Well the asyncio error has an IPv4 one. I'm not sure what else you're asking.
