我正在使用 SDL_mixer 完成本关于音频的教程，一切都很顺利。

之后我决定去实验、玩、摸索，所以我做了一个非常相似的程序，有两个声道，让我播放一些视频游戏音乐，并按下按钮播放游戏音效。

然后我开始玩得开心和按动按钮，只是为了愚蠢并测试程序。我开始非常快速地将多个按钮混合在一起，然后在这样做了大约 5 秒后，程序意外关闭。

从大约 2 个月前的那个日期开始，我一直无法在使用 SDL_mixer 的计算机上运行任何东西。我尝试使用 SDL_mixer 创建新项目，我重新下载了所有 SDL 和 SDL_mixer，甚至在 sdl 论坛上提出了这个问题。

我正要重新格式化我的整个计算机以使其再次工作，这是 - 不 - 好的。扩展库不应该强迫某人重新格式化，尤其是当这是一个可能会传递给最终用户下载和使用程序的问题时。

我使用的是 Windows 7 64 位；微软 Visual Studio 2012 专业版；C++；和 SDL 1.x

另外，如果有人知道出了什么问题，我该如何解决这个问题，防止它再次发生，并安全地使用声音，这样我就不会在用户的计算机上造成问题？

我用来初始化混音器的行如下：

//Initialize SDL_mixer 
if( Mix_OpenAudio( 22050, MIX_DEFAULT_FORMAT, 2, 4096 ) == -1 ) 
{ 
    return false; 
}

启动程序后调试器吐出的行并立即关闭：

PS 有没有一种更简单的方法来表示大段代码，而不必在每行前面手动复制过去 4 个空格？这花了一段时间._.;

感谢 genpfault 的建议，我能够找到解决此问题的方法。

事实证明，解决方案是当程序从过载的声道崩溃时，因为必须通过按键激活声音，排队的按键被附加到程序的源代码中，因为 Visual Studio 会自动崩溃后抓住“窗口焦点”并“抓住”多余的字符。

这些字符恰好在程序一开始就被附加到 SDL_mixer 函数的第一个错误检查行之一的字符串文字中，因此它不会为编译器抛出语法错误；错误检查行只是说“不，加载的文件与此字符串不完全匹配，因此关闭程序”，这导致程序在我的断点可以注册并允许我调试之前退出。

终于解决了这个问题，这绝对是一种解脱。

谢谢 genpffault 和 stack-overflow！~
