 Please report this upstream, it is plain broken code.
 
 #define hash_item_data(item) ((HASHDATA *)((char *)item + sizeof(ITEM)))
 
 is obviously broken for all architectures where alignement of HASHDATA
 and ITEM differ.
 
 Let upstream decide on what they like best as a fix.
 
 Maybe something like
 
   struct item_data {
     ITEM item;
     HASDATA data;
   };
 
 and then letting the compiler do the homework.
