Following code crashes:
<code>
class T {
        @property {
                float[3] scale() {
                        return [1, 2, 3];

                void scale(float[3] value) {
                        float tx = 1;
                        writeln(tx, " ", tx, " ", tx,
                                tx, " ", tx, " ", tx,
                                tx, " ", tx, " ", tx);

Similar:
<code>
writeln(tx, tx, " ", tx, tx, " ", tx, " ", tx, tx, " ", tx, " ", tx);
</code>
<result>5.93185e-395.89226e-39 11 1 11 1 1</result>

Ps. i can't pick field 'version' 2.054 (above 2.041)
