It sounds like the new metadata is violating the assumptions of ThinLTO dead symbol analysis. We drop the symbols marked dead in the index based on global analysis, but the metadata is still referencing them, which leads to bad assumptions later when those declarations still exist in the IR. Presumably they became dead after earlier inlining? I don't know much about the new metadata.
