I'm getting this failure (below) from validate fairly consistently. It is often silenced by adding an empty file ghci/should_run/T13456.stderr But it's troubling. Does anyone else see this? How can I debug it?
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.
