--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- The issue is that 'dest' is NULL so we build NULL.a which of course can't work. 8845 /* We need source and destination components. */ 8846 comp = fold_build3_loc (input_location, COMPONENT_REF, ctype, decl, 8847 cdecl, NULL_TREE); 8848 dcmp = fold_build3_loc (input_location, COMPONENT_REF, ctype, dest, 8849 cdecl, NULL_TREE); 8850 dcmp = fold_convert (TREE_TYPE (comp), dcmp); 8851
