Nothing changed wrt the build configuration compared to previous successful builds a few weeks earlier. For now we suspect some random corrupted download - I'll restart the build, but want to log this occurrence here. Maybe @yarikoptic can find similar events in archived logs.

Attaching full log from the failed run.

Re-running the Appveyor build helped, so the only explanation I can find is butterfly wings causing a disturbance that flipped a bit on a drive platter (https://xkcd.com/378/) - or, more seriously, randomly corrupted download?

Since the problem failed to replicate, I suppose nothing can be done other than closing this issue.
