You have an error in your code - you aren't pointing to a proc object at all. See below.

Don't do the above - this is what is getting you into trouble. Instead, do this:

orte_proc_t *procptr1, *procptr2;
orte_node_t *node;

if (NULL == (procptr1 = (orte_proc_t*)opal_pointer_array_get_item(jdata->procs, proc.vpid))) {

      ORTE_ERROR_LOG(ORTE_ERR_NOT_FOUND);
      return; /* or whatever */
}
node = procptr1->node;

for (i=0; i < node->procs->size; i++) {
    if (NULL == (procptr2 = (orte_proc_t*)opal_pointer_array_get_item(node->procs, i))) {
>

          ORTE_ERROR_LOG(ORTE_ERR_NOT_FOUND);
          return; /* or whatever */
    }
     if (procptr2->name.jobid == procptr1->name.jobid &&
         procptr2->name.vpid == procptr1->name.vpid) {
             /* procptr2 now points at your proc struct, so set your value */
             procptr2->my_value = foo;
             break;
     }
}

Remember, the proc objects are -not- stored in vpid order in the node->procs array, so you have to search that array to find the one you want.
