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.
I've added GC.collect and GC.minimize() at the end of each frame,
looks like the growth has stopped, so its not a 32-bit problem
yet.
