<pre>Consider this program:
#include <functional>
#include <string>
int main() {
std::bind(&std::string::c_str, std::string());
return 0;
}
Building with Clang against libc++ fails at link time, because string::c_str is
not implemented. As a pointer to the function escapes, I would expect a weak
link_once implementation to be emitted.</pre>
