As ando already said: .....it tries to lookup a database to relay for when unbinding, but unbind has no DN, so a strcmp on NULL is performed. This does not happen when using the "relay" directive because relay database selection does not occur for each operation....

configuration example: database bdb suffix "dc=real,dc=naming,dc=context" .... .... .... database relay suffix "" overlay rwm suffixmassage "dc=real,dc=naming,dc=context"
