The question is: can we do that change and what the second assert of field's 
flags is used for?
The assert is there to guard against unintended use of this nullptr-marker
mechanism.

I have tested so this should work. By the way a vmstate test covering this
corner-case would be a good idea too (IMHO). Would you like to write one?
Sorry, I don't know how to write that test case. Can you please write one?
thanks!
The test is just nice to have, but we definitely need the fix!
Ok, I'll send out the discussed fix patch.
