following error:

clang++-10 -stdlib=libc++ main.cc

#include <memory>

int main()
{
    int a;
    std::raw_storage_iterator<int *, int> i(&a);
    std::iterator<std::output_iterator_tag, void, void, void, void> *p = &i;
}

main.cc:7:70: error: cannot initialize a variable of type
'std::iterator<std::output_iterator_tag, void, void, void, void> *' with an
rvalue of type 'std::raw_storage_iterator<int *, int> *'                       
 std::iterator<std::output_iterator_tag, void, void, void, void> *p = &i;
