C Valgrind报告SDL2内存泄漏
这是我第一次与vlagrind合作，我想知道这些错误是否是令人担忧的，我应该担心还是忽略它们。我的程序只是一个简单的SDL22D太空游戏，我不知道这些内存泄漏是从哪里来的C Valgrind报告SDL2内存泄漏,c,sdl,valgrind,C,Sdl,Valgrind,这是我第一次与vlagrind合作，我想知道这些错误是否是令人担忧的，我应该担心还是忽略它们。我的程序只是一个简单的SDL22D太空游戏，我不知道这些内存泄漏是从哪里来的 ==9173== Conditional jump or move depends on uninitialised value(s) ==9173== at 0xA0E1343: ???

有人能解释一下这些错误是什么意思吗？不幸的是，这种库总是有一些漏洞。您可以在SDL/OpenGL/任何您想要的图形库上查看更多详细信息或找到更多答案，但长话短说，这几乎总是会发生的。 您应该关注的所有漏洞都可以追溯到您自己编写的代码
我建议启动
