template <typename, typename>
struct AAA{};

template<typename ...Args>
void f(AAA<Args...> *) {}

int main() {

此代码导致编译错误.使用g++ -std=c++1z错误编译时显示如下:

prog.cc: In function 'int main()':
prog.cc:8:24: error: no matching function for call to 'f<int, int>(std::nullptr_t)'
     f<int, int>(nullptr);
                        ^
prog.cc:5:6: note: candidate: template<class ... Args> void f(AAA<Args ...>*)
 void f(AAA<Args...> *) {}
      ^
prog.cc:5:6: note:   template argument deduction/substitution failed:
prog.cc:8:24: note:   mismatched types 'AAA<Args ...>*' and 'std::nullptr_t'
     f<int, int>(nullptr);

使用clang++ -std=c++1z错误是:

prog.cc:8:5: error: no matching function for …
