--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Arguably, if LANG_TYPE is now what is supposed to survive till end of
compilation for the std::meta::info objects, we need to stream LANG_TYPE in and
out.
decltype (^^::) a {};
-std=c++26 -freflection reproduces it too.
I guess I can try to handle it in LTO streamer then.
