3221225477 is 0xC000005 (Access Violation). I think this is equivalent to a segmentation fault so there's a real bug somewhere.

@nodejs/platform-windows.

[joyeecheung]

I tried resuming Windows a few times lately and all of them failed because of this error on Windows + ARM - and it's almost constantly failing as far as I can tell from CI history. I think we should mark it as flaky for Windows + ARM for now. On a side note it would be easier to debug the test if it's split instead of putting all the test cases together in one file.

[joyeecheung]

Maybe someone from @nodejs/wasi is up for splitting that test? It seems that could be rewritten with custom configuration in python instead, which would also help making the test run faster by running the test cases in parallel (currently it takes 3.7s to run on a beefy laptop, in the CI on Windows this takes ~15s)

#51836 shows that only the test case of poll() is flaking.
