How do I enable sanitizers with Clang?

To enable sanitizers with Clang, you can use specific compiler flags during the build process. Sanitizers are tools that help detect various kinds of errors, including memory leaks, undefined behavior, and data races. Here’s a simple guide on how to enable them.

Enabling AddressSanitizer

To enable AddressSanitizer, use the following flags:

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

Enabling MemorySanitizer

To enable MemorySanitizer, use these flags:

clang -fsanitize=memory -g -o my_program my_program.cpp

Enabling ThreadSanitizer

For ThreadSanitizer, compile your code as follows:

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

Running the Program

To run your program with sanitizers, simply execute it in the terminal:

./my_program
