test_asyncio started to crash at build 491: http://buildbot.python.org/all/#/builders/58/builds/491 This build contains the commit f23746a934177c48eff754411aba54c31d6be2f0: "bpo-32436: Implement PEP 567". I'm not 100% sure that it's the cause of the regression. Since test_context added by this commit also crash, it really smells this the cause of the regression. |

It's not a regression, the newly added code doesn't work on some Windows buildbot... looking at it. |

No, these are trivial uint32_t/Py_SIZE: `for (uint32_t i = val_idx + 1; i < Py_SIZE(o); i++)`; it's something else. I suspect popcount instruction... |

I suspect this is a compiler bug. I can't reproduce it on my windows 7 virtual machine and on AppVeyor. It's not related to HAMT, btw, as there is a multitude of HAMT-specific tests that all pass. The crash is specifically in context.c, and the code there is pretty trivial. |

> I suspect this is a compiler bug. It may be interesting to add the compiler version to test.pythoninfo. It would be simpler to compare Windows buildbots to identify a bug. Currently, the only info is: "sys.version: 3.7.0a4+ (heads/master:9d411c1, Jan 23 2018, 15:13:42) [MSC v.1900 32 bit (Intel)]" Some environment variables are also dumped: os.environ[VS100COMNTOOLS]: C:\Program Files\Microsoft Visual Studio 10.0\Common7\Tools\ os.environ[VS140COMNTOOLS]: D:\Program Files\Microsoft Visual Studio 14.0\Common7\Tools\ os.environ[VS90COMNTOOLS]: D:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\ In the compile step, I see lines like: "Microsoft (R) Build Engine version 14.0.24730.2" I recall also issues with outdated ucrtbase DLLs. Maybe we can also dump the version of such DLL? |

In an off-list conversation with David, it was confirmed that the buildbot in question runs on an old hardware without SSE4.2 support. I decided to simply stop using native popcount instructions as there's no detectable performance difference when using them vs using the fallback code. See https://github.com/python/cpython/pull/5292 for details. |

> I've pushed a commit that should fix the buildbot. Please reopen if it doesn't. test_context and test_asyncio do'nt crash anymore on this buildbot, thanks Yury. test_asyncio still fail on this buildbot, I created a new issue: bpo-32645, test_asyncio: TLS tests fail on "x86 Windows7" buildbot. |
