The following code crashes Clang 3.4.2 under Arch Linux x86-64:
////////////
template <typename T>
const auto select2nd = std::bind(&T::value_type::second, std::_1);
int main() {
std::map<int, int> m;
std::vector<int> v;
std::transform(m.begin(), m.end(), std::back_inserter(v),
select2nd<std::map<int, int>>);
return 0;
}
////////////
