[Mpi-forum] Interest of changing lower bound in MPI_Type_create_resized

Hi, In MPI_Type_create_resized we can change the extent and the lower bound. I don't understand what is the interest of changing the lower bound, since for sending message, only the extent is used. Is there an example where the value for lower bound in MPI_Type_create_resized have a real impact ?
