Indeed this is odd. I have not seen this in CI or my local
builds. It's possible that I have seen it in local builds that were failing
for other reasons but ignored it.

While I don't know why you are seeing these failures in general, the
fact that they are reported as framework failures is arguably a bug. I
would argue that we should treat a non-existing .stderr file as we would
an empty file. I've opened !3121 fixing this. Hopefully you will see a
more helpful error message with this patch.
