Compiler hang when initializing large std::arrays

Question

I need to initialize a very large multidimensional std::array of data:

class Thing;

class World
{
public:
    World() : space{nullptr} {};
             


        

Answer 1

vector>>> space;

and when initializing it:

for (int i = 0; i < 1000; i++)
{
   vector>> sp1;
   for (int j = 0; j < 1000; j++)
   {
      vector> sp2;
      for (int k = 0; k < 1000; k++)
         sp2.push_back(make_unique("params", "to", "construct", "thing"));

       sp1.push_back(move(sp2));
   }

   space.push_back(move(sp1));
}

It is similar to your approach, but it constructs the vectors in the heap instead of stack.
