程序启动后马上关闭，编译器出现内存泄露警告，为何？

vs2010的c++内存泄露检查工具，可定位到出错代码行、开源免费工具。

内存泄露Demo leaky app

LeakDiag是一个监测内存泄漏的工具，可以用来精确地找到内存泄露一直到代码行。它使用微软的Detours 技术，拦截指定内存分配的调用并跟踪各种调用栈，并报告已分配但尚未释放的内存，这一信息允许让我们在排除一个内存泄露问题时，能精确查看哪些组件进行了该分配。使用正确的调试符号，我们甚至可以看见请求分配的代码行。

一、首先回顾一下内存泄漏是什么：内存泄漏是指：程序已经不再使用某字段、某对象。但是却无法回收掉它占用的内存。两个关键点：不再使用并且无法回收二、为什么ThreadLocal会发生内存泄漏问题？ 2.1 问题发现以下是整体结构 ThreadLocal就相当于一个访问工具类，通过操作ThreadLocal对象的方法来操作存储在当前线程内部的ThreadLocalMap里的值 ThreadLocalMap是一个哈希数组，key为ThreadLocal对象，Value为一个Objec

本文介绍了高效诊断和优化 Java 内存泄漏问题的系统化方法。通过获取内存快照、使用 MAT 和 JProfiler 等工具分析对象，逐步排查泄漏源，确认问题并优化代码，开发者可以解决内存泄漏并提升应用性能。内容包括内存快照生成、内存差异对比、疑似泄漏检测、代码优化等，确保垃圾回收机制正常工作，最终提高应用的稳定性和效率。
