Rebuilding Core’s Link Database on Sitecore 9.0 Update 1 generates lots of errors

When rebuilding the Link Database for the Core database on Sitecore 9.0 Update 1 (XP0 configuration), I received 630 errors!

The Link Database rebuild continues, and appears to complete successfully. I didn’t see any problems arising from this, but 630 errors is quite a lot.

I was also able to replicate this on several different development systems for different customers.
