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();
}
