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

Ok, i can't explain the nuance of why g++ is puking on this, but until you work that out, consider this for your member declaration:

std::vector,size>,size>> space;

and in the constructor initializer list:

World() : space{size}

That should at least get you compiling and move all this to the heap. Note: this better be a 64bit process. I'm going to have to hunt to find out why g++ is doing what I suspect it is doing.
