I compiled Python 3.6 in debug mode on Windows, and I'm trying to run test_regrtest to try to reproduce a bug. The problem is that the test opens a million of popup. Clicking on Ignore is useless, the popup continues to reappear again and again. The stderr is also flooded with "Assertion error ..." with the MSCRT. I don't understand the usage of this popup and this error message. Python already raises a nice OSError when a FD is invalid. Can we please always turn these warnings off even in debug mode when calling a MSCRT function protected by _Py_BEGIN_SUPPRESS_IPH/_Py_END_SUPPRESS_IPH? See also issue #25001 "Make --nowindows argument to regrtest propagate when running with -j".

By the way, these warnings are flooding buildbot output, it became really hard to read these logs :-( Extract: minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false minkernel\crts\ucrt\src\appcrt\time\wcsftime.cpp(1182) : Assertion failed: false

See also the issue #25306 "test_huntrleaks_fd_leak() of test_regrtest hangs on Windows". It may be caused by this issue.

See also issue #23919, this issue may be a duplicate of this one.

It is a direct duplicate of multiple issues. The assertion is coming from the CRT, because their definition of "undefined behaviour" includes displaying an assert dialog in debug mode, and last time we tried disabling them completely we upset people. (I'm not 100% clear how you get from "closing an already-closed fd" to "undefined behaviour", but I assume it's an interpretation of invalid parameters.) I'll get the patch for issue 23919 together, based on what Zach described in issue 25001.
