mem leaks win32 call_back

first, apologies if i'm posting to the wrong place

version : Euphoria Interpreter 4.0.0 beta 2 (r2670) for Windows

using the following code under win32
causes memory leaks when viewed under Process tab
of Windows Task Manager.

include dll.e 
 
function callback_routine() 
   return 0 
end function 
 
procedure test_callback(sequence rname, integer loopcount) 
   atom headfunc, writefunc 
   headfunc  = routine_id(rname) 
   writefunc = routine_id(rname) 
   headfunc  = call_back({ '+', headfunc }) 
   writefunc = call_back({ '+', writefunc }) 
   printf (1, "loop = %4d\n", { loopcount }) 
end procedure 
 
--// main 
   integer i = 1 
   while (1) do 
      test_callback("callback_routine", i) 
      i += 1 
   end while 

the memory leaks can be traced to call_back( ...) function call.

after taking a look at the sources (.c and dll.e) it does appear
that call_back is allocating memory for function pointer handles
under windows.

is there any way to reclaim the memory allocated?

i am almost complete with writing an LGP (linear genetic programming)
library, that uses call_back() extensively (loads eui dlls as plugins,
then fixes up function pointers)


TIA
