hashtable...squid

I work with the bit-vector(http://search.cpan.org/dist/Bit-Vector/)
and squid lib as well. But I meet a weird situation now...Let's see my
code.
I wanna creat a hashtable in a function, and then return the address of
the hashtable.
But my hashtable looks empty outside the fake_table().
The hashtable just manage the pointer I insert. Don't really "copy"
anything into the table.


hashtable *fake_table(){

BitVector_Boot();
N_char x1[] = "101000";
N_char x2[] = "101010";

wordptr X1 = BitVector_Create(6, 1);
wordptr X2 = BitVector_Create(6, 1);

BitVector_from_Bin(X1, x1);
BitVector_from_Bin(X2, x2);

hash_table *inst_table =
hash_create(inst_tb_compare,7951,hash_string);
hash_table *ht2 =
hash_create(inst_tb_compare,7951,hash_string);

inst_tb_atom *_atom1 = (inst_tb_atom
*)malloc(sizeof(inst_tb_atom));
inst_tb_atom *_atom2 = (inst_tb_atom
*)malloc(sizeof(inst_tb_atom));

_atom1->_type = 1;
_atom1->point_to.ht = ht2;
_atom1->X = X1;

_atom2->_type = 1;
_atom2->point_to.ht = ht3;
_atom2->X = X2;

hash_insert(ht2,x2,_atom2);
hash_insert(inst_table,x1,_atom1);

return inst_table;
}

Thanx!!!
