--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I am not sure this is an errant error though. you assign k from things[i][j] and then access things[k][j]. Well GCC could figure out things.stuff is all zero but currently does not . BUT I suspect the original code was much more complex than this.
