11 UndefinedBehaviorSanitizer (UBSan) is a fast undefined behavior detector.
12 UBSan modifies the program at compile-time to catch various kinds of undefined
33 Use ``clang++`` to compile and link your program with ``-fsanitize=undefined``
46   % clang++ -fsanitize=undefined test.cc
86      ``-fsanitize=local-bounds`` is not included in ``-fsanitize=undefined``.
96      zero. This is undefined per the C and C++ standards, but is defined
98      infinity or NaN value, so is not included in ``-fsanitize=undefined``.
111      Issues caught by these sanitizers are not undefined behavior,
117      Issues caught by this sanitizer are not undefined behavior,
131      to an incompatible type. This is often unintentional, but is not undefined
132      behavior, therefore the check is not a part of the ``undefined`` group.
136      This will also detect some types of undefined behavior that may not

199   -  ``-fsanitize=integer``: Checks for undefined or suspicious integer
208      nullability does not have undefined behavior, it is often unintentional,
