Hi,

I faced the following problem with xeno 2.5.x , but may exist on other 
releases .

1/ I create a rt_heap
2/ in this rh_heap I alloc many named "data area"
I always give the global rt_heap ptr. no problem, areas are allocated.

3/problem arises when unallocating/unbinding
using rt_heap_free/rt_heap_unbind.
only the last segment created is freed. Because the global heap ptr size 
contains only size of the last allocation.


============================
to solve the problem, I had to use a distinct rt_heap for each named 
area, in this case.

At first, I may have misunderstood the way was working rt_heaps ?
I was thinking I could manage only a heap with many named modules inside 
it...

Regards
