        PR lto/89692
        * tree.c (fld_type_variant, fld_incomplete_type_of,
        fld_process_array_type): Call fld->pset.add and don't call
        add_tree_to_fld_list if it returns true.
        (free_lang_data_in_type): Similarly with self-recursive call.  Purge
        non-marked types from TYPE_NEXT_VARIANT list.
        (find_decls_types_r): Call fld_worklist_push for TYPE_CANONICAL (t).

        * g++.dg/other/pr89692.C: New test.
