Occurred while making modifications https://git.lix.systems/lix-project/lix. I'm not quite sure what happened here, I think somehow the in memory representation became a whole bunch of zeroes and clang got extremely confused. It went away after rebuilding. Suspect this might have something to do with precompiled headers? (gut feeling)
