To Be or Not to Be: Object Lifetime Issues and Related Tools
Whether an object should “to be or not to be” is a question every C++ programmer must pay close attention to. Object lifetime is a fundamental concept in C++, and misunderstandings about it are the root cause of many coding errors. Unlike Rust, C++ cannot reject code with lifetime issues at compile time, but we can still use various tools to help identify and prevent lifetime-related problems. This talk will cover the basic concepts of object lifetime, analyze common pitfalls, and introduce tools and techniques that can assist developers in detecting and avoiding lifetime issues in C++ programs.
