Hi,

The next code snippet fails in session mode.
I can create and allocate heaps from a program.
In another one, I can bind , but rt_heap_inquire fails with Invalid 
argument.
Or I can use rt_alloc_heap with it. But when accessing memory, a bus 
error is trapped.


     //err = rt_heap_bind(heap_desc[module],module,TM_INFINITE);
     err = rt_heap_bind(heap_desc[module],module,TM_INFINITE);
     if (err != 0)
          {
          printf("can not bind %s [%s]\n",module,strerror(-err));
          return (void *) -1;
          }


//    err = rt_heap_inquire(heap_desc[module],&info);
//    if (err != 0) {
//        printf("can not inquire info about %s 
[%s]\n",module,strerror(-err));
//        return (void *) -1;
//        }
//      printf("size %d\n,",info.heapsize);

     err = rt_heap_alloc((RT_HEAP *)heap_desc[module],4288,TM_INFINITE, 
&shmem);
     if (err == 0)
         {
         return shmem;
         }
     else {
          printf("can not alloc %s [%s]\n",module,strerror(-err));
          return (void *) -1;
          }
