    Weird Error - [SOLVED]

    Im making a project for school and im stuck at this one part. Im trying to use a vector of objects that i defined. But i want the vector of objects to be declared inside a class declaration and then initialized inside the constructor of that class. Here is my code:

    Code:
    #ifndef MAP_H
    #define MAP_H
    
    #include "waypoint.h"
    
    class Map
    {
    public:
    	Map();
    	~Map();
    	void initMap(); // this will create the ocean floor and water top in a glList
    	void DrawGround(GLfloat); // the y position that the ocean floor will be drawn
    
    	void DrawWaypoints();
    
    private:
    	/* DISPLAY LISTS */
    	GLuint ground;		// Storage For The net_box Display List
    
    	GLfloat floor_width;
    	GLUquadricObj *quadratic;	// Storage for this->quadratic objects
    
    	std::vector<Waypoint> way_vec;
    };
    
    #endif
    that is my class declaration called map.h. You can see i am declaring a vector of Waypoints which is a class i defined and included at the top of the file. Now in map.cpp where i declare my constructor i want to push Waypoint obejcts onto the vector like this:

    Code:
    ...
    #include "map.h"
    
    Map::Map()
    {
            Waypoint test = Waypoint(10.0, 20.0, 6.0);
    	way_vec.push_back(test);
    }
    ...
    Now if i do that everything compiles fine but when i run the program in visual studio's 2005 i get a pop up error saying

    "windows has triggered a breakpoint in pathfinder.exe

    This may be due to the corruption of the heap, and indicates a bug in pathfinder.exe or any of the DLLs is has loaded.

    The out put window may have more diagnostic information"

    I really do not get why is is giving me this error. I think it has something to do with declaring a vector of waypoints in the class definition because if i just write in int main()

    Code:
            vector<Waypoint> way;
    	Waypoint obj = new Waypoint(10.0, 10.0, 2.0);
    	way.push_back(obj);
    that works just fine.

    Does anyone know what im doing wrong?
