Hi Ralph,

I did valgrind and found uninitialised value errors. All of them
occured in opal_tree_add_child as shown at the bottom. As a quick
fix, I puted one line in "opal_tree.c", although it's not elegant:

void opal_tree_init(opal_tree_t *tree, opal_tree_comp_fn_t comp,
                    opal_tree_item_serialize_fn_t serialize,
                    opal_tree_item_deserialize_fn_t deserialize,
                    opal_tree_get_key_fn_t get_key)
{
    tree->comp = comp;
    tree->serialize = serialize;
    tree->deserialize = deserialize;
    tree->get_key = get_key;
    opal_tree_get_root(tree)->opal_tree_num_children = 0 ; /* added by
tmishima */
}

Then, these errors all disappeared and openmpi with lama worked fine.
As I told you before, I built openmpi with PGI 13.10. As far as I
checked, no error was detected by valgrind with openmpi built by
GNU compiler. Therefore, it might depend on compiler...
Anyway, I would like to ask you (or openmpi team) to continue
further investigation.

Regards,
Tetsuya Mishima
