Benedict commented on CASSANDRA-8792:
-------------------------------------

I would prefer the caller to enforce this where necessary, since there's no 
good reason to absolutely refuse an empty memory object, so we may 
unnecessarily break something. If we in future have to relax it, we also run 
the risk of doing so inconsistently and relying on the assumption elsewhere.

I don't feel too strongly one way or the other though.

> Null pointers are valid returns if a size of zero is returned. We assume a 
> null pointer implies resource mismanagement in a few places. We also don't 
> properly check the bounds of all of our accesses; this patch attempts to tidy 
> up both of these things.
