The above is a direct RTL call. But note that
a) it is buggy in case of multi-threaded programs: http://bugs.freepascal.org/bug_view_advanced_page.php?bug_id=14315
b) it won't contain any information at all if you use cmem or another  
memory manager that does not keep track of allocation information.
