Broken since 78417b5, this bug creates an infinite recursion at runtime while trying to resolve the QPromise<T> template constructor if the given callback is either an invalid function or a valid callback but using auto args (C++14).
Related warning: C4717: recursive on all control paths, function will cause runtime stack overflow.
