按任意键时 GLFW 崩溃（分段错误（核心转储））

Question

使用glfw与glad和stb_image渲染一个带有纹理的矩形（遵循learnopengl.com），但是在我获得矩形渲染后，GLFW崩溃并在调用glfwPollEvents时抛出段错误，但仅当我按下键盘上的任何按钮时。关闭或调整窗口大小效果很好。

预期结果没有发生，因为我没有任何输入函数来做事情。我尝试重写我的脚本但仍然崩溃 这是main.cpp：

void setUp() {
    cout<<"Setting up..."<<endl;
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    stbi_set_flip_vertically_on_load(true);
}
int cleanUp(GLFWwindow* window, uint vao, uint vbo, uint ebo) {
    cout<<"Cleaning up..."<<endl;
    glad_glDeleteVertexArrays(1, &vao);
    glad_glDeleteBuffers(1, &vbo);
    glad_glDeleteBuffers(1, &ebo);
    glfwDestroyWindow(window);
    glfwTerminate();
    return 0;
}
int main() {
    setUp();
    cout<<"Hi, mum!"<<endl;

    GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "Hi, mum!", NULL, NULL);
    if(window == NULL) {
        cout<<"Failed to create window!"<<endl;
        glfwTerminate();
        return 1;
    }
    glfwMakeContextCurrent(window);

    if(!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress)) {
        cout<<"Failed to init GLAD!"<<endl;
        glfwTerminate();
        return 2;
    }

    glad_glViewport(0, 0, WIDTH, HEIGHT);

    Shader shader = newShader(DEFAULT_VERTEX_SHADER_PATH, DEFAULT_FRAGMENT_SHADER_PATH);

    uint vao;
    uint vbo;
    uint ebo;
    glad_glGenVertexArrays(1, &vao);
    glad_glGenBuffers(1, &vbo);
    glad_glGenBuffers(1, &ebo);

    glad_glBindVertexArray(vao);

    glad_glBindBuffer(GL_ARRAY_BUFFER, vbo);
    glad_glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW);

    glad_glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, ebo);
    glad_glBufferData(GL_ELEMENT_ARRAY_BUFFER, sizeof(indices), indices, GL_STATIC_DRAW);

    // position attribute
    glad_glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)0);
    glad_glEnableVertexAttribArray(0);
    // color attribute
    glad_glVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)(3 * sizeof(float)));
    glad_glEnableVertexAttribArray(1);
    // texture coord attribute
    glad_glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, 8 * sizeof(float), (void*)(6 * sizeof(float)));
    glad_glEnableVertexAttribArray(2);

    uint texture;
    glad_glGenTextures(1, &texture);
    glad_glBindTexture(GL_TEXTURE_2D, texture); // all upcoming GL_TEXTURE_2D operations now have effect on this texture object
    // set the texture wrapping parameters
    glad_glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); // set texture wrapping to GL_REPEAT (default wrapping method)
    glad_glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
    // set texture filtering parameters
    glad_glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR);
    glad_glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    // load image, create texture and generate mipmaps
    int width, height, nrChannels;
    unsigned char *data = stbi_load("data/myimage.png", &width, &height, &nrChannels, 0);
    if (data)
    {
        glad_glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, data);
        glad_glGenerateMipmap(GL_TEXTURE_2D);
    }
    else
    {
        cout<<"Failed to load texture"<<endl;
    }
    stbi_image_free(data);


    while(!glfwWindowShouldClose(window)) {
        glad_glClearColor(0.2f, 0.3f, 0.4f, 1.0f);
        glad_glClear(GL_COLOR_BUFFER_BIT);

        glad_glBindTexture(GL_TEXTURE_2D, texture);

        useShader(shader);
        glad_glBindVertexArray(vao);
        glad_glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_INT, 0);

        glfwSwapBuffers(window);
        cout<<"Before poll!"<<endl;
        glfwPollEvents();
        cout<<"After poll!"<<endl;
    }


    return cleanUp(window, vao, vbo, ebo);
}

我知道它会在 glfwPollEvents 崩溃，因为如果我运行代码然后按下按钮，控制台会输出以下内容：

Before poll!
After poll!
Before poll!
After poll!
Before poll!
Segmentation fault (core dumped)

矩形使用纹理渲染，没有问题

Answer 1

newShader 内部调用了一个函数，该函数尝试读取着色器文件，但没有正确分配内存来读取它。
