void main() {
    int x;
    switch ('x') {
        case 'a':
            x++;
        case 'b': .. case 'c':
            x++;
            break;
        default:
    }
}



With dmd 2.063alpha it compiles with no errors nor warnings. But I think it
should give an error like:

test.d(6): Error: switch case fallthrough - use 'goto default;' if intended
