Re: [OMPI users] Uncommitted MPI_Datatype leaks memory heavily

[Ilja Honkonen]

Get the free out of the #ifndef LEAK and your problem will be solved.
        for (int i = 0; i<  10000000; i++) {
                MPI_Datatype type;
                assert(
                        MPI_Type_contiguous(
                                10 * sizeof(double),
                                MPI_BYTE,
                                &type
                        ) == MPI_SUCCESS
                );
                #ifndef LEAK
                assert(MPI_Type_commit(&type) == MPI_SUCCESS);
                assert(MPI_Type_free(&type) == MPI_SUCCESS);
                #endif
        }

Thanks, so it's a feature. A bit surprising though since usually local 
variables are deallocated automatically.
