--- Comment #5 from tbanelwebmin at free.fr ---
I came across something similar.
The following program crashes on assert,
but only when compiled with -O
DMD64 D Compiler v2.068.0

----------------------------
struct SomeStruct
{
  void fff (int n)
  {
    SomeStruct next;
    assert (&next != &this);
    if (n)
      next.fff(n-1);
  }
}

void main()
{
  SomeStruct root; 
  root.fff(2);
}
----------------------------

As a workaround, add
  return 3;
at the end of fff
and change void to int
