If you're getting the latter, that's a bug and we should fix it. Are you building from source? Have you run the tests? The DRC now has a pretty comprehensive set of test cases, and I would expect this to be flagged. A quick test with 4.2.0 on Win10 flags this correctly.

DRC should care about copper only unless there are special flag or similar indicating it is OK of course.
