Constructing a value based on a type and address might change the type of the newly constructed value. Thus re-fetch type via value_type to ensure we have the correct type at hand. * ada-lang.c (ada_value_primitive_packed_val): Re-fetch type from value. (ada_template_to_fixed_record_type_1): Likewise. (ada_to_fixed_type_1): Likewise. * cp-valprint.c (cp_print_value_fields_rtti): Likewise.
