The following throws an Access Violation exception under windows when compiled
with dmd -release -O

int get_value()
{
    return 1;
}

int[2] array1;
int[2] array2;

int test(ulong a1, ulong extra, ulong extra2, ulong extra3)
{
    if (!((a1 & 1) | (get_value() | array1[a1^1])))
        return 0;

    if (0 >= array2[a1^1])
        return 0;

    return 1;
}

void main(char[][] args)
{
    test(0, 0, 0, 0);
}

Tested with dmd 1.033, 1.041, 1.043, 1.053
