问boost::interprocess::managed_shared_memory崩溃程序EN本故事纯属虚构。 初入职场的小木，负责维护一个博客系统，后端采用C++编写，部署在Windows服务器上。刚刚熟悉完产品的小木，接到了后台服务的报警，服务器后端偶尔会程序崩溃。刚开始小木还有点慌张，脑子里面浮现出各种问题，这个是程序的bug吗？茫茫的代码如何...

Thus, a unified memory access model is made possible in which the methods for a computing entity to access a regular object in managed memory is similar to how the computing entity accesses shared memory.TAILLEFER Martin
