Valgrind warns that *newtype is uninitialized when calling from
Fortran as e.g.
use mpi
integer :: t, err
call MPI_Type_create_f90_integer(5, t, err)
Since newtype is intent(out), this should not happen. There is
no reason to convert the type using PMPI_Type_f2c, only to over-
write it immediately afterwards. The other type_create_* functions
did not convert newtype.
The valgrind warnings:
