Windows task manager shows constantly increasing memory usage of my D application, yet there is ZERO allocation done by it at the time. I have made a hook inside the rt/lifetime.d for _d_allocmemory, and I do get notified when an array or a class object in constructed. What could be the source of rapidly climbing (hundred kilobytes per second) memory usage?
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.
