C++20 is experimental still in GCC as a whole, see
https://gcc.gnu.org/projects/cxx-status.html#cxx20. coroutines are still on the
rougher edge of that, although Iain, Arsen, and others have been doing a lot of
work on trunk for that (for 15). I don't know how many of those fixes are
backportable though.
This particular bug was marked as a dupe of PR101367 which is fixed in GCC 13+.
We can ask Iain and Arsen if the patch would be OK to backport, though.
