There are templates: for example

    void print1(auto x){std::cout<< x;}

is a function template

    template <class T>
    void print1(T x){std::cout<< x;}

This is not valid C++14 however, so it doesn't compile. If you replace these, you'll probably still get a stack overflow while expanding the templates because there are almost 7000 arguments to a single function call.

It is "valid C++" IF there are fewer arguments, like 6-10

The example illustrates C++ internal representation of "variadic functions".

I was referring to the use of generic functions (ie. with an argument with type-specifier auto) which is not C++14. Your copy of g++ may accept it as an extension.

And that works if you use the old C style variadic functions?I suppose I see no reason why it wouldn't, but that isn't the same.
