When allocating MemoryError classes, there is some logic to use pre-allocated instances in a freelist only if the type that is being allocated is not a subclass of MemoryError. Unfortunately in the destructor this logic is not present so the freelist is altered even with subclasses of MemoryError.. (cherry picked from commit 9b648a95ccb4c3b14f1e87158f5c9f5dbb2f62c0) Co-authored-by: Pablo Galindo <Pablogsal@gmail.com>
