How do I use Address/Leak/Thread/Undefined sanitizers with Clang?

Using AddressSanitizer, LeakSanitizer, ThreadSanitizer, and UndefinedBehaviorSanitizer with Clang is essential for debugging your C++ programs. These sanitizers help to identify various issues in your code, ensuring enhanced reliability and performance. Below are quick guides and examples on how to use these sanitizers effectively.

Using AddressSanitizer

To use AddressSanitizer with Clang, compile your program with the `-fsanitize=address` flag:

clang++ -fsanitize=address -g -o my_program my_program.cpp

Using LeakSanitizer

LeakSanitizer works in conjunction with AddressSanitizer and detects memory leaks. Use the same flag, `-fsanitize=address`:

clang++ -fsanitize=address -g -o my_program my_program.cpp

Using ThreadSanitizer

To enable ThreadSanitizer, compile with the `-fsanitize=thread` flag:

clang++ -fsanitize=thread -g -o my_program my_program.cpp

Using UndefinedBehaviorSanitizer

For UndefinedBehaviorSanitizer, compile your code with the `-fsanitize=undefined` flag:

clang++ -fsanitize=undefined -g -o my_program my_program.cpp

By using these sanitizers, developers can capture runtime errors and undefined behaviors effectively, improving their overall software quality.
