--- Comment #2 from Johannes Larsen <mail at johslarsen dot net> ---
There seems to be a similar issue related to comparisons of iterators for
containers of std::expected. This minimal examples gives the same GCC 15/trunk
warning:

#include <expected>
#include <vector>
int main(int argc, char *argv[]) {
    std::vector<std::expected<int,int>> results{};
    return std::begin(results) == std::end(results);
}
