--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r10-6110-g8158a4640819dbb3210326e37786fb874f450272 , before that
the vars have been mangled - _ZZ2f1E1f, _ZZ2f2E1f .
BTW, I get an ICE instead of assembler-failure:
pr93643.C:25:1: error: Two symbols with same comdat_group are not linked by the
same_comdat_group list.
