I am wondering when we can drop support for g++-8. All supported operating systems, except for CentOS Stream 8 offer a greater version:

• Ubuntu Focal: gcc 9 (https://packages.ubuntu.com/focal/gcc)
• Debian Bullseye: gcc 10 (https://packages.debian.org/bullseye/gcc)
• CentOS 8 Stream: gcc 8, with EOL of " May 31st, 2024 " (https://www.centos.org/centos-stream/)

The rationale for dropping it would be that there are currently occasional compile failures with perfectly valid C++-17 code, for example:

• error: call to non-‘constexpr’ function ‘void __assert_fail(const char*, const char*, unsigned int, const char*)’ assert(false); (https://godbolt.org/z/bxaMnfcsa)
