 UndefinedBehaviorSanitizer (UBSan) is a detector of non-portable or erroneous program constructs which cause behavior which is not clearly defined in the ISO C standard. UBSan provides a large number of sub-options to enable / disable individual checks for different classes of undefined behavior. Consult the GCC[^gcc-instrumentation] and Clang[^clang-ubsan] documentation respectively for up-to-date information on supported sub-options.
