Subject: [Bug libstdc++/114891] Unconditional use of std::is_pointer_interconvertible_base_of_v in <generator> makes the header unusable with Clang 18
Date: Tue, 30 Apr 2024 04:18:05 +0000	[thread overview]

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So a C++23 library header (generator) is using a C++20 feature
(is_pointer_interconvertible_base_of_v) ...

Especially since GCC 14.1.0 will most likely be released with this header and
14.2.0 won't come out until Summer end (around most likely around the same time
as clang 19). And GCC 15.1.0 won't come out until April/May 2025.
Supporting older clang which does not have C++20 support for something which is
C++23 (which itself won't fully be supported until GCC 15 at earliest).
