Are there any chances for it to be fixed for gcc-11 or gcc-10.3? This feature

Oh sorry, it seems I forgot to attach a preprocessed file. I am not able to
find it now so please close this issue.
Sorry for the trouble.

It might be a regression because I remember it working fine. Now it fails
again. Check here: https://godbolt.org/z/-K39X7.
