@Andreas-Krebbel any comments on this discrepancy between C and C++ in GCC?   Was this intentional?

> Both clang++ and g++ aligns this to 16 bytes:
> `std::atomic<__int128> Atomic_int128;         // C++`
>
> However, while clang aligns this also to 16 bytes, GCC aligns only to 8, which I suspect is an error by GCC(?):
> `Atomic __int128 Atomic_int128;               // C`
