[OMPI users] Parallel I/O doesn't work for derived datatypes with Fortran 90 interface

When I try to use parallel I/O routines like MPI_File_write_at or MPI_File_read_at with the buffer argument being a derived datatype, I am unable to compile and just get an error of the nature: MPI_FILE_READ_AT(fh, offset, buffer, count, datatype, status, ierr) 1 Error: There is no spe
