FS#556 - GenericReferenceElements leak memory
User who did this - Martin Nolte (nolte)

----------
I think this is a singleton-problem. The singleton GenericReferenceElement internally uses the singleton SmallObjectPool. Now, gcc creates the singletons the the order I stated. Hence, the singletons are deleted in the inverse order. Therefore, SmallObjectPool cannot free up the memory that is still used by the GenericReferenceElement.

Everything would be fine, if SmallObjectPool were created before GenericReferenceElement. Then, the destruction would be the other way round.

Actually, this is not a real problem, though. The SmallObjectPool is designed to allocate memory on demand and only free it on program termination. It is annoying, though.
