Address (ASAN) and Undefined Behavior (UBSAN) Sanitizers

Enable ASAN and UBSAN (for Clang/GCC) by adding these flags to compiling and linking options

# CMakeLists.txt
target_compile_options(SanitizerProject PRIVATE -fsanitize=address -fsanitize=undefined)
target_link_options(SanitizerProject PRIVATE -fsanitize=address -fsanitize=undefined)

Get UBSAN (runtime error) and ASAN output

$ mkdir build && cd build
$ cmake .. && make
$ ./SanitizerProject 2> ../sanitizer_err.txt

Switch macro on and off for either seeing ASAN or UBSAN errors

// main.cpp:8
#if 1

Thread Sanitizer

Similar to ASAN and UBSAN, just add a compiling and linking option

# CMakeLists.txt
target_compile_options(SanitizerProject PRIVATE -fsanitize=thread)
target_link_options(SanitizerProject PRIVATE -fsanitize=thread)

Get thread sanitizer output

$ mkdir build && cd build
$ cmake .. && make
$ ./ThreadSanitizerProject 2> ../sanitizer_err.txt
