Yes. I found the place where objects' states are consistent. And it works well.
Thank you for your answers, they helped me a lot.

I would like to find a place where all objects in MOS are marked as
live/dead, but before
compactisation. May such state be produced by playing with
num_marking_collectors ?
Or is there any appropriate method to produce such state (for further
MOS iteration)?
