--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The problem is that references_to_redirect contains ipa_ref_t and those ipa_ref_t nodes live in the referring node->ref_list.references vector. If there is more than one reference with ref->referring == node, then we need to ensure we process them from the one which appears last in node->ref_list.references vector.
