The tree is already different for cp_parser_identifier (called via <-
cp_parser_class_name <- cp_parser_type_name <- cp_parser_simple_type_specifier
<- cp_parser_postfix_expression <- ... <- cp_parser_jump_statement).

I think I annotated (printf debugging) all code which sets TYPE_BINFO or
TYPE_NEEDS_CONSTRUCTING - without seeing a difference. Still, the setting
differs for _Res.


[Ideas how to debug this best are welcome; as reducing it didn't work, it is
easy to get lost.]
