--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Your custom quiet NaN is not a quiet NaN, but signaling NaN.
And, as documented, -fno-signaling-nans is the default.
If you change your custom signaling NaN into a quiet NaN,
static constexpr std::uint64_t kCustomNaN = 0x7ff8000000000000 | kMagicNumber;
or if you compile with -fsignaling-nans, this works fine, so I'd say this is
just a user error.
