Based on the error you get from rosrun tf tf_echo base_link map, I would guess that the odom<->map and base_link<->odom transforms are in different time epochs. That would explain why each transform seems to work but trying to concatenate them doesn't.

Can you verify that both the odom<->map and base_link<->odom transforms have similar timestamps (you may need to inspect the output of the /tf topic) or double check whatever node you have that is outputting base_link<->odom .
