| ; copy is handled properly. Specifically, the local copy will be promoted, |
| ; and internalization should be able to use the original non-promoted |
| ; name to locate the summary (otherwise internalization will abort because |

| ; Note that gold picks the first copy of weakfunc() as the prevailing one, |
