I run into this. This is always the same and it happens randomly when one loads the inventory, I am using direct 3d and AGS 3.2.1, there were some inventory items that had either no sprites (thus a bigbluecup appeared instead) or were 16bit sprites while the game is 32bit. Is there a way to find out the exact line that's causing the crash by those pointers?

Now that we have an engine source this became little easier.
"Program pointer" is a special value that is being set throughout the engine (called our_eip).
our_eip = +379;
eip_guinum = 1; (from gtags)
eip_guiobj = 0; (from gtags)

Code: cpp

GUIMain::draw_at(int xx, int yy)
{
  <...>

  SET_EIP(379)

  for (aa = 0; aa < numobjs; aa++) {
    
    set_eip_guiobj(drawOrder[aa]);

    GUIObject *objToDraw = objs[drawOrder[aa]];

    if ((objToDraw->IsDisabled()) && (gui_disabled_style == GUIDIS_BLACKOUT))
      continue;
    if (!objToDraw->IsVisible())
      continue;

    objToDraw->Draw();

    int selectedColour = 14;

    if (highlightobj == drawOrder[aa]) {
      if (outlineGuiObjects)
        selectedColour = 13;
      wsetcolor(selectedColour);
      draw_blob(objToDraw->x + objToDraw->wid - get_fixed_pixel_size(1) - 1, objToDraw->y);
      draw_blob(objToDraw->x, objToDraw->y + objToDraw->hit - get_fixed_pixel_size(1) - 1);
      draw_blob(objToDraw->x, objToDraw->y);
      draw_blob(objToDraw->x + objToDraw->wid - get_fixed_pixel_size(1) - 1, 
                objToDraw->y + objToDraw->hit - get_fixed_pixel_size(1) - 1);
    }
    if (outlineGuiObjects) {
      int oo;  // draw a dotted outline round all objects
      wsetcolor(selectedColour);
      for (oo = 0; oo < objToDraw->wid; oo+=2) {
        wputpixel(oo + objToDraw->x, objToDraw->y);
        wputpixel(oo + objToDraw->x, objToDraw->y + objToDraw->hit - 1);
      }
      for (oo = 0; oo < objToDraw->hit; oo+=2) {
        wputpixel(objToDraw->x, oo + objToDraw->y);
        wputpixel(objToDraw->x + objToDraw->wid - 1, oo + objToDraw->y);
      }      
    }
  }

  SET_EIP(380)
  <...>
}

BTW, I like how "Illegal Inception" sounds .

EDIT: If you can run engine and your game in MSVS debugger, you could find exact point. Also you may give your game to some of the active devs for a test.
EDIT2: I've actually forgot about the dump. I guess it can be used to check the program state at the moment of exception.
