[Cython] cython 0.23.4 test failure, async_iter_pep492 (), asyncio_generators, test_async_def_future.py

[Dimitri John Ledkov]

Hello,

Building 0.23.4 fails on ubuntu with python 3.5.

Full build log is at:
https://launchpadlibrarian.net/228728126/buildlog_ubuntu-xenial-amd64.cython_0.23.4-0ubuntu1_BUILDING.txt.gz

First with 2.7, run.asyncio_generators are skipped. Then there is a
successful run of asyncio_generators (?!) and then a failed one (?!)

The what i think relevant portion of the build log is as follows:

async_iter_pep492 ()
Doctest: async_iter_pep492 ... ok
test_aiter_raises (async_iter_pep492)
Doctest: async_iter_pep492.test_aiter_raises ... ok

Doctest: async_iter_pep492.test_broken_anext ... ok

test_for_2 (async_iter_pep492)
Doctest: async_iter_pep492.test_for_2 ... ok

runTest (__main__.CythonRunTestCase)
compiling (c) and running attr ... attr ()
Doctest: attr ... /usr/bin/python3.5 test_async_def_future.py

Traceback (most recent call last):
  File "test_async_def_future.py", line 16, in <module>
    runloop()
  File "test_async_def_future.py", line 14, in runloop
    assert events == expected, events
AssertionError: ['setup', 'setval', None]

ok

Any help resolving this would help. Is this a broken python3.5? or
cython? or both?
