Fair enough - there's not harm in putting local symbols in dwo sections, since they won't be emitted into dwo files anyway - but yeah, no reason to.

Knowing what the assert was might be interesting. (perhaps we do make the simplifying assumption and assert that there aren't labels in dwo sections, but I don't think so... - I think we do assert that there aren't any /relocations/ in dwo files)
