On Boost 1.81 with clang 18 in C++ 23 mode:
```
[build] /usr/include/boost/fiber/future/detail/shared_state.hpp:160:19:
warning: 'aligned_storage<4, 4>' is deprecated [-Wdeprecated-declarations]
[build] 160 | typename std::aligned_storage< sizeof( R), alignof(
R) >::type storage_{};
[build] | ^
[build] /usr/include/boost/fiber/future/promise.hpp:28:22: note: in
instantiation of template class
'boost::fibers::detail::shared_state<int>' requested here
[build] 28 | typedef typename shared_state< R >::ptr_type ptr_type;
```
It could have been fixed upstream since, I haven't checked.
