This D2 code asserts with dmd 2.042:


void foo(int[] ra) {
    ra[0] = 20;
}
int[] bar() {
    int[] data = [10];
    foo(data);
    return data;
}
void main() {
    int[] r1 = bar();
    assert(r1[0] == 20);
    enum int[] r2 = bar();
    assert(r2[0] == 20); // Assertion failure
}


This is quite important, because it introduces silent bugs.
It can be related to bug 1330.
