In case anyone wants to learn more how ASan works, I wrote a blog post on it at https://blog.trailofbits.com/2024/05/16/understanding-addres...

It also explains that the fact ASan works well with, e.g., std::vector in C++ doesn't come for free and if you want ASan to detect bugs when your custom collections or allocators are used you have to use special ASan API to mark [in]accessible memory.
