From fpdf_parserh.h, the following are all contiguous arrays indexed by object 
number:

    CFX_FileSizeArray   m_CrossRef;
    CFX_ByteArray       m_V5Type;
    CFX_FileSizeArray   m_SortedOffset;
    CFX_WordArray       m_ObjVersion;

Soo ... should your pdf happen to contain large sparse object numbers, the size 
of these will bloat. Unclear if any document generators actually produce such 
documents.
