--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
C++17 support was not stablized until GCC 9.x.
from: https://gcc.gnu.org/gcc-9/changes.html
The C++17 implementation is no longer experimental.
So we can say this is won't fix.
The patch which caused the ABI break is here:
https://gcc.gnu.org/pipermail/libstdc++/2017-December/046672.html
Which was done after GCC 7 but before GCC 8.
The ABI was not stabilized until GCC 9.x so we knew the break was ok at that
point.
