            Bug ID: 40266
           Summary: instantiating a non-type class template with
                    no-linkage object as argument cause clang to crash

                OS: MacOS X

crash backtrace

struct StringObject{
  constexpr StringObject(const char*ptr){}
};

template<StringObject const&stringObject>
struct String{};

int main(){
  String<StringObject{"string"}> obj{};
}


a non-type class template with reference or pointer type must instantiate a
different class templates for each object that get passed to it as an argument
with the above code clang get crashed trying to instantiate a class template
instance with an object with no linkage

****NOTE****: clang is working fine and producing an error with
(-std=c++11,-std=c++14) and don't crash but crash when compiling the code with
(-std=++1z)

the above source code was compiled with only (-std=c++1z) compiler flag
