Would it be possible to create a looped pointer in C++?

For example, a series of pointers such as the following:
Pointer A -> Pointer B -> Pointer C -> Pointer D -> Pointer B

Would the compiler recognise this as a problem and remove it? What would be the consequences of trying to access this pointer?

Just a thought...

wouldn't really be a huge problem. 'looped pointers' exist in code 'naturally' in abstract data types such as doubly linked lists. it would loop for as many times as you tried to dereference the pointer. it's not a problem really so no, the compiler shouldn't complain since as i said 'looped pointers' exist legitly in code anyway

I suppose. I was looking at it from a view of "give application ptr1 and it'll go through the pointer list until it reaches the data", though this doesn't actually happen since it'd just look at what the pointer went to once and that would be that.

How would CE's pointer scanner handle such a structure? Would it be limited by the depth parameter?

It's called a Circularly Linked-List:

Thanks

I actually knew about circularly linked lists, but had forgotten that they worked by having a list of looped pointers.
