<pre>The test program
==== begin test program ====
#include <vector>
#include <ranges>
void
f(std::vector<int> vec) {
for (auto& e : vec | std::ranges::views::drop(1)) {
}
}
==== end test program ====
Does not compile on clang, either with libc++ or libstdc++, failing on some
enormously complicated constraints. gcc accepts it.</pre>
