Question

当我尝试调试使用SDL2的代码时出现了问题。我正在使用GDB，出于某些原因无论我做什么，当我尝试在遇到断点后继续调试时程序突然崩溃。这只在调用任何SDL2方法时发生，否则，它可以正常工作。

这是脚本代码：

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

#define SDL_MAIN_HANDLED
#include <SDL2/SDL.h>

const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;

int main(int argc, char** argv)
{
    if (SDL_Init(SDL_INIT_EVERYTHING) != 0) {
        printf("Could not initialize!");
        return -1;
    }

    SDL_Window* win = SDL_CreateWindow("Hello, World!", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);
    if (win == nullptr) {
        printf("Could not create window!");
        SDL_Quit();
        return -1;
    }

    bool quit = false;
    SDL_Event e;
    SDL_Surface* surface = SDL_GetWindowSurface(win);
    SDL_FillRect(surface, nullptr, SDL_MapRGB(surface->format, 0xff, 0xff, 0xff));

    while (!quit) {
        while (SDL_PollEvent(&e) != 0) {
            if (e.type == SDL_QUIT) {
                quit = true;
            }
        }

        int i = 0;
        i++;
        SDL_UpdateWindowSurface(win);
    }

    SDL_DestroyWindow(win);
    SDL_Quit();
    return 0;
}

这是在断开点崩溃之前反汇编中的程序集。

我使用的是64位版本的TDM-GCC（包括调试器）和SDL2。

无法在Code :: Blocks中调试SDL2程序
