Please point out on particular code. The autotester log shows failures in phobos testing, but there is no output, so it is not clear what exactly is happening.
Issue 1567 seems to be fixed long time ago.

The autotester deletes old build logs, which is what happened there. Since the PR is closed, I don't think it's going to try building it again.
