All structural elements have geometrical flaws, and in concrete structures tolerances are measured in centimetets/inches. Alignment issues may result in problems if they are not addressed in design time (i.e. buckling) but that sort of scenario is very basic. Even european construction standards directly address geometrical flaws. They may look ugly but they're not exactly a problem. Breaking a build, however, is a major problem.
