--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> --- Created attachment 41758 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41758&action=edit Tentative patch I'm not sure how this is supposed to be fixed. But this is a point fix that at least allows lto1 to finish. I'm currently testing if that also makes the test-case pass.
