Teaching Containers and Allocators How to Sanitize Addresses - Miro Knejp - CppNorth 2023
Many people have probably heard of, and used, address sanitizer (ASAN), a tool integrated into many compilers to detect memory corruption bugs or the use of dangling pointers. But what many do not know, is that ASAN also has a runtime API. With it you can integrate its address verification mechanism into your own classes, like containers or allocators, to increase the safety of consuming code.
After a brief introduction into the internals of ASAN we will look at a custom container where ASAN does not catch out-of-bounds access and how to remedy it using the runtime API. We will further look into unit testing your integration, take a look at a more C++-friendly wrapper of the basic C-based API, and cover some gotchas when integrating it with allocators.
