        <pre>I get the following ICE when trying to compile the following code that uses
"boost::container::small_vector" (I can reproduce this with clang trunk for
Boost 1.58 and Boost 1.61):

#include <boost/container/small_vector.hpp>
#include <type_traits>

using boost::container::small_vector;

struct A : small_vector<int, 3> {
  using vector_t = small_vector<int, 3>;
  using vector_t::vector_t;
  using vector_t::operator=;
};

template <typename P> inline void foo(P) {
  small_vector<P, 3> pls;
  pls.push_back(P{});
}

int main() {
  foo(A{});
  return 0;
}</pre>
