--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
There is a reason why GCC does not implement this "undefined" sanitize is
because it is not undefined code to wrap for unsigned integer.
It is bad that clang/LLVM implements it and people now think it is undefined
and report bugs like this.
