Subject: [OMPI devel] Error after ompi-restart

Hi All,

I think that exists an error in the trunk version while trying to
restore a checkpoint.

The function orte_util_decode_pidmap while attempts to execute the
following code

    /* store the data */
    for (i=0; i < num_procs; i++) {
        pmap.node = nodes[i];
        pmap.local_rank = local_rank[i];
        pmap.node_rank = node_rank[i];
        opal_value_array_set_item(procs, i, &pmap);
    }

produces a segmentation fault

[nodo2:18027] *** Process received signal ***
[nodo2:18027] Signal: Segmentation fault (11)
[nodo2:18027] Signal code: Address not mapped (1)
[nodo2:18027] Failing at address: (nil)

I was trying to trace the problem and I think that it occurs in the line
opal_value_array_set_item(procs, i, &pmap);

Thanks,
