 > The external logic check in here appears to be wrong. The check is
 applied when the code sees the need to insert a new element in the
 underlying representation 'in the middle' -- the lower bound does not
 return end, and and the slot it returns does not have the correct index.
 The check requires the map to be empty or that the iterator is at the end,
 thus refusing to insert into the middle.

 I see your point. Can you provide an example where the check fails
 although it should succeed?

 (BTW: No one seems to use map_array any more because std::map can be used
 instead.)
