--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Jonathan Wakely from comment #4) > Use -fsanitize=undefined to diagnose the undefined behaviour at runtime, or > use -fwrapv to make the negation well-defined (both options are suggested by > https://gcc.gnu.org/bus/ which you were asked to read before creating a new > bug report). Oops, that should be https://gcc.gnu.org/bugs/
