void swap(int[]* lhs, int[]* rhs)
{
    *lhs = *rhs;
    *rhs = *lhs;
}

int ctfeSort()
{
     int[][2] x;
     swap(&x[0], &x[1]);
     return 0;
}

void main()
{
    enum x = ctfeSort();
}


Causes a stack overflow with dmd master (2.054)
The same thing happens when using references.


void swap(ref int[] lhs, ref int[] rhs)
{
    lhs = rhs;
    rhs = lhs;
}

int ctfeSort()
{
     int[][2] x;
     swap(x[0], x[1]);
     return 0;
}

void main()
{
    enum x = ctfeSort();
}
