Adding elements into tree data structure

[Iyer, Balaji V]

Hello Everyone,
        I would like to add 8 integer array fields (I am also OK if they are 
tree-lists) into the tree data structure. I want to update this fields every 
time I see loops. This value will be used later by the optimizer. I tried to 
just add them into the structure in tree.h (under struct tree_base) and it is 
seg-faulting. I am using GCC 4.6.0.

        Can someone please tell me the procedure for adding elements into the 
tree structure?

        Any help is highly appreciated!

Thanking You,

Yours Sincerely,

Balaji V. Iyer.
