Description

The following program sometime produces Exception ignored in: <object repr() failed> when quit

import asyncio
async def coro(name):
    await asyncio.sleep(1)
    print('coro {}: waiting for lock'.format(name))

loop = asyncio.get_event_loop()
coros = asyncio.gather(coro(1), coro(2 ))
loop.run_until_complete(coros)
loop.close()
quit()

Here is output of the program above.
