A jump to a labelled statement (case xxx and default are labelled statements) is not permitted to bypass the initialisation of an object a variable.

                break ;

            case 7 : // *** error: cannot jump from switch statement to this case label
                     // *** error: jump bypasses initialisation of 'int j'
                ;
                // ...
        }

        if( i < 10 ) goto label ; // *** cannot jump from this goto statement to its label

        int k = 6 ;
        ++k ;

    label:  ; // // *** error: jump bypasses initialisation of 'int k'
