RTEMS (via newlib) does use the heap so this is not completely true.

If an application did not allocate any memory from the heap, I think you would still 
need to provide a heap for libc plus other code to work. For example I think a printf 
call results in an stdio buffer being allocated. I also know the DOSFS uses the heap.

I remember meantion of a heap size call so maybe a test of:

void Init ()
{
   print_heap_usage ();
}

would be worth a try.
