It was due to deliberate dangling inside some of the tests, which caused CI to terminate prematurely (I believe in `libcxx/test/std/containers/views/views.span/span.cons/array.pass.cpp`).

I figured checking this inside tests didn't make much sense, so I demoted it to a warning to get CI going. I'm not sure how you'd like it to be handled long-term.
