Any idea why it suddenly started to fail?

I don't know. Could it be a different version of Git Bash?

@nodejs/build-infra were the Windows hosts updated recently?

What is the value of os.EOL? For windows I expecte it to be \r\n and wonder why cutting it down to just \n allows the test to pass.

If you look at the error message here: https://ci.nodejs.org/job/node-test-binary-windows-js-suites/12290/RUN_SUBSET=3,nodes=win2012r2-COMPILED_BY-vs2019-x86/testReport/junit/(root)/test/parallel_test_child_process_pipe_dataflow/, you'll notice that the difference between the actual and the expected character count is 1023. That error can only happen if there is an additional (or missing) character per line, so I guess for some reason \r is not handled correctly.

That would make sense if somewhere in the flow '\r\n' is getting converted to '\n'.

I think it's the grep command not playing well with \r\n.

I don't see any issues related to updating the Windows machines, but I'm not sure if they would update themselves @joaocgreis do you know.

Either way its worth getting the tests running again as long as this passes on all windows machines.

I don't see any recent PRs that might have changed related behaviour in Node.js itself.

I remember having problems with the non-Windows tools under Windows a while ago. Eventually, we might want to switch to binaries that are native to Windows and not provided by msys.
