The reason for the failure is that for

arr2D[0].insert(1);

the opIndex() method is invoked which returns by value. In theory this is okay
since the array is stored by reference and the returned value contains a
reference to the payload data of the inner array.

What happens here is that arr2D[0] is uninitialized (the pointer to the
RefCounted object is null) and this guy is returned. It is then changed (the
insert method initializes the temporary and creates the ref-counted object with
the inserted content).

One way to resolve this is to make opIndex return a reference. Or is there an
alternative?
