Scene Load Crash

[reepblue]

On most situations, I get a crash when loading a map. I first discovered this on a complex project and I thought it was me doing something stupid. Turns out, on a very basic project, the problem still happens.

#include "Leadwerks.h"

using namespace Leadwerks;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Leadwerks", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    auto scene = LoadScene(world, "Maps/Start.map");

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        world->Update();
        world->Render(framebuffer);
    }

    return 0;
}

This has something to do with the Lua binding code being too big for the stack. When I declare this before the call to LoadScene, the program works correctly:

GetLuaState();

Specifically, it's crashing in the Entity class binding code, which is probably the class with the most methods.

Another option is to increase the stack reserve size in the project settings:

Properties->Configuration Properties->Linker->System->Stack Reserve Size

The default value is one MB. Set this value to 4194304 to change it to four MB.
