How do I use sanitizers (ASan, UBSan, TSan, MSan)?

Sanitizers are powerful debugging tools that help identify various types of errors in C++ programs. Here’s a brief overview of the different sanitizers you can use in your C++ projects:

AddressSanitizer (ASan)

AddressSanitizer is used to detect memory corruption errors such as buffer overflows and use-after-free errors. To compile your code with ASan, use the following flags:

UndefinedBehaviorSanitizer (UBSan)

UndefinedBehaviorSanitizer helps you find undefined behaviors in C++ code, like integer overflow or null pointer dereferences. Compile your code with:

ThreadSanitizer (TSan)

ThreadSanitizer detects data races in programs that use multithreading. You can enable TSan by compiling your program with:

MemorySanitizer (MSan)

MemorySanitizer is used to detect uninitialized memory reads in C++ programs. To compile with MSan:

To link against the sanitizers, make sure you have the appropriate libraries installed and linked, as some sanitizers might require additional options.
