Possibly. But why would this effect only indexes?

This is the same error that was also reported on GENERAL recently on
8.0.1.

I'm suspicious of a more subtle intermittent error. We have no
information about what the magic values are, only that they are not
correct. Should we increase the information returned for that error?
That might show up an error cause.
