segmentation fault (core dumped)

Hi, i run ubuntu 14.04LTS 64-bit this i what i get when i try to compile this program:

// GLEW
#define GLEW_STATIC
#include <GL/glew.h>
// GLFW
#include <GLFW/glfw3.h>

int main(void)
{
    //Initilization
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);

    GLFWwindow* window = glfwCreateWindow(800, 600, "LearnOpenGL", nullptr, nullptr);
    glfwMakeContextCurrent(window);

    glewExperimental = GL_TRUE;
    glewInit();

    glViewport(0, 0, 800, 600);

    //Gameloop
    while(!glfwWindowShouldClose(window))
    {
        glfwPollEvents();
        glfwSwapBuffers(window);
    }

    glfwTerminate();

    return 0;
}

i don't know why, this is how i compile it:

first i do this: g++ -c first.cpp -std=c++11
second i do this: g++ first.o -o first.exec -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -lGLEW

and simply : ./first.exec

    glewInit();

    cout << "did glewInit\n";

    // Define the viewport dimensions
    glViewport(0, 0, 800, 600);

    cout << "Going in to the game loop\n";

    // Program loop
    while(!glfwWindowShouldClose(window))
    {
        // Check and call events
        glfwPollEvents();

        // Render
        // Clear the colorbuffer

        //glClearColor(0.2f, 0.3f, 0.3f, 1.0f);
        //glClear(GL_COLOR_BUFFER_BIT);

        // Swap the buffers
        glfwSwapBuffers(window);
    }

    glfwTerminate();
    return 0;
}

// Is called whenever a key is pressed/released via GLFW
void key_callback(GLFWwindow* window, int key, int scancode, int action, int mode)
{
    cout << key << endl;
    if(key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
        glfwSetWindowShouldClose(window, GL_TRUE);
}

this is my new code and it gives dumped right after the made window, i didn't do this before because i didn't know it happens in middle of program (i thought it doesn't start at all)

this is gdb result :
