我已经运行了以下命令并杀死了报告给它的所有泄漏和错误，但我仍然在程序完成执行后得到一些随机的free(): invalid pointer。
valgrind -v --tool=memcheck --leak-check=full --track-origins=yes --show-reachable=yes ./blah
这是我修复“一切”后的输出：

还有什么我可以尝试跟踪这个随机+我的程序执行后，神秘无效免费？
编辑：
退出之前的最后2行......
applog("GODDAMN IT");
return final_rc;

这是我为free: invalid pointer获得的“通知”：

通常会发生这种情况，当您意外删除由静态或全局对象拥有的对象时，将尝试在main()完成后释放它。
更喜欢使用std::shared_ptr<>或std::unique_ptr<>，具体取决于拥有指针的所有权，以及非拥有指针的原始指针。然后你的代码中任何明确的delete都是代码气味。 delete需要一个原始指针，它只能是一个非拥有指针，所以代码的另一部分拥有这个对象，应该注意删除它。
