That does sound strange.

Oh good, it's not just me :)

How easily can you reproduce it? That majorly effects how I would try to debug something like this...

No idea. Looking at the builds on Pipelines again, it seems that all the builds since about 10am PDT have been failing, so perhaps they rolled out something that changed how umask works? I don't have any idea whether that's possible though.

If you're able to get an strace of a failed run then that would probably tell us a lot.

I'll need help with that :) But if it's just commands in the .azure-pipelines/posix-steps.yml file then sending a PR with them added should do it.

Though given there seems to be a clear start time and no relevant change, I'm inclined to report it to the Pipelines team (which I already have) and see what they say. Normally my internal CPython builds catch issues in the hosted VMs before they reach public accounts, but this may have been a hotfix for some other issue.

Cheers, Steve
