--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I am with terrible internet connection and it still does not reproduce for me
(I suppose difference between GNU LD and gold).
It is however clear what happens, we try to add symbol's alias that is external
and we do not expect external symbols to be in partitions.
Does the following (untested) help?
