For this particular test I used the current master (022a9d8). I reread the MPI_T chapter and [as usual] there might be something that cautions the current behavior (aka. returning MPI_T_ERR_INVALID_INDEX for an index smaller than the number of cvars returned by MPI_T_cvar_get_num). This is indicated by the example 14.4, page 576. If I exclude this return code from the list of errors, then things are working as expected.
What is the community feeling? Should we reutrn the exact number of available cvars or an upper bound is a valid value? George.
