This is basically the same problem as #2888.
I don't know how to use MSVC-STL-trunk with Compiler Explorer, but the following code should be rejected incorrectly.
#include <ranges>
struct Bool {
Bool& operator!();
Bool() = default;
Bool(const Bool&) = delete;
operator bool() { return true; };
};
int main() {
Bool b;
int x[] = {42};
auto r = std::views::iota(0, 5) | std::views::chunk_by([&](auto, auto) -> Bool& { return b; });
r.begin();
}
