What is ASAN?

AddressSanitizer (ASan) is a fast memory error detector. It detects use-after-free, heap-buffer-overflow, stack-buffer-overflow, use-of-after-scope, global-buffer-overflow, use-of-uninitialized-memory, memory leaks, and other memory errors. It works by instrumenting memory accesses to detect errors at runtime, making it invaluable for debugging and ensuring memory safety in C/C++ code.
