动态库主要提供一些运行时的复杂的功能(比如 poison/unpoison shadow memory)以及将 malloc/free 等系统调用函数 hook 住。 AddressSanitizer 基本使用 根据AddressSanitizer Wiki 可以检测下面这些内存错误 Use after free:访问堆上已经被释放的内存 Heap buffer overflow:堆上缓冲区访问溢出 Stack buffer overflow:栈上缓...

LeetCode的常见内存报错便也是上面几种之一,不过LeetCode不检查内存泄漏,现在我们主要关注这几种:heap-buffer-overflow(堆溢出)、stack-buffer-overflow(栈溢出)、heap-use-after-free(释放后使用)、global-buffer-overflow(全局变量溢出)、SEGV on unknown address(非法内存)。
