Yes, this is the problem, thanks Avrina!

I see... Probably this can be configurable option (use GC or RC 
for algorithms internals) or can be inferred from the data type 
properties (like use RC if data methods used for algorithm are 
@nogc). But I'm not sure if this is possible and whether it makes 
practical sense.
