If your programm is a 32-bit application the GC most likely leaks memory 
because it thinks its still referenced. Try compilling your application 
for 64-bit. If the problem goes away it's not your fault.
A possible workaround for this situation is to allocate large blocks of 
memory which you know will not contain any pointers with GC.malloc 
manually and specifying the "don't scan" flag.

If the problem still exists in a 64-bit application you most likely 
continue to allocate memory that remains referenced. Make sure you don't 
have any infinitly growing arrays or other containers that still 
reference the memory you allocated.
