This is not valid code, I assume you mean make_shared<char*>()
That creates a char* and initializes it as a null pointer, so *c == nullptr.

Please post a complete working example showing the problem, not
incomplete pieces of code that cannot be compiled. That means you must
show the code including all headers, 'using namespace std' etc.
