Shmuel,

 yes, looks like this was unnecessary, because this still doesn't  
change anything. Still the same error message. The code I'm running is:

for i=100,1,-1 do
    aRoom = Room.new()
    print( tostring( aRoom ) )
    aRoom = nil
end

I've set the C++ object to printf "room created" and "room deleted"  
from its constructor/destructor. The exact output I'm getting is:

room created
attempt to concatenate a userdata value
room created

Does that ring a bell for anyone? I'm simply puzzled :-(
