SDL or OpenGL unexpected behavior (Process termiated with status -1073741510 (o minutes, 6 seconds))

Question

I have the following code and it compiles successfully but when I execute the program the following message appears.

Process terminated with status -1073741510 (0 minute(s), 3 second(s))

What am I doing wrong?

here's the code:

#include <SDL.h>
#include <stdio.h>
#include <stdlib.h>

#ifdef WIN32
    #define WIN32_LEAN_AND_MEAN
    #include <windows.h>
#endif // WIN32

#if defined(__APPLE__) && defined(__MACH__)
    #include <OpenGL/gl.h>
    #include <OpenGL/glu.h>
#else
    #include <GL/gl.h>
    #include <GL/glut.h>
#endif // defined
