Stcuk with Unhandled exception at 0x00007FF74F27A526 : Stack Overflow

I am having stack overflow related exception. To be clear on that, I have no recursive function that can lead to blowing up stack. Although somewhere in my application I am creating a huge array with std::array and I am using class templates.

I thought of doing allocating memory dynamically but that is the last thing I want to do, also in template function which causing me the problem goes like this:

//class Template
template <class T, int Point, int End>
class Node;
private:
int Point;
int End;
std::array <T, Point*End>;
public:
// Rest of the stuff!
//Operator defined in class
//End of Node object1 is equal to Point of Node object2 always so;

template <int entry>
Node<T,Point,entry> operator* (const Node<T,End,entry> &source)
{
  Node<T,Point,entry> temporary_node(0.);

//for_loop to multiply each element store in std::array

return temporary_node;
}

It is important to mention that my array size is somewhere around 10000000.

1. What is the solution if I don't want to use dynamic memory allocation:

   • Let's say if I do, then how can I allocate memory dynamically for temporary node in * operator defined above, as it takes up memory for vector when I do this:

     Node temporary_node;

2. I am on Windows and I also don't want to increase stack size manually as going over 1MB manually will solve the problem but It will be risky and maybe buggy.

Thank you in advance.
