--- Comment #1 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- Looks like a dup of PR66880. richi said in that bug: »It would be better to make the C FE reject this as constant expression which invokes undefined behavior. IMHO -fsanitize should never sanitize any constant expression - the FE will reject non-constant ones anyway.« I agree. No compiler (icc, clang, gcc) warns about it.
