Hi all,

valgrind-3.16.0.RC2 doesn't work for me (as previous version on this
server). 

_*My fortran test program (error prune I think) is as simple as:*_

    PROGRAM reduce
    USE mpi
    IMPLICIT NONE

    INTEGER :: me,  ncpus, ierr
    REAL :: buff,  resu=0

    CALL MPI_INIT(ierr)
    CALL MPI_COMM_RANK(MPI_COMM_WORLD,me,ierr)
    CALL MPI_COMM_SIZE(MPI_COMM_WORLD,ncpus,ierr)
    buff=1

    CALL MPI_ALLREDUCE(buff,resu,1,MPI_REAL,MPI_SUM,MPI_COMM_WORLD,ierr)
    if (me == 0 ) WRITE(6,'(a,i0,2(a,f14.6))') 'On ',me,' I have
    ',buff,' and got ',resu

    CALL MPI_FINALIZE(ierr)

    END PROGRAM reduce

_*Compilation with:*_

mpifort reduce.F90 -o reduce
mpifort --show
/opt/GCC73/bin/gfortran -I/opt/openmpi-GCC73/v3.1.x-20181010/include
-pthread -I/opt/openmpi-GCC73/v3.1.x-20181010/lib -Wl,-rpath

-L/opt/openmpi-GCC73/v3.1.x-20181010/lib -lmpi_usempif08
-lmpi_usempi_ignore_tkr -lmpi_mpifh -lmpi

_*OS is *_CentOS Linux release 7.7.1908 (Core)

_*Valgrind compiled with gcc7.3, configure options are:*_

    ./configure --enable-only64bit --with-mpicc=$(which mpicc)
    --prefix=/robin/data/begou/VALGRIND/valgrind-binaries

*Hardware is:*

    Dell Poweredge R940

    4 x Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz (laubnched Q3 2017)

    1.5 TB of RAM

_*Compiler*_ is gcc (GCC) 7.3.0 (january 2018)

_*OpenMPI *_is

    v3.1. from the git repo 2018/10/10 (because a patch was needed at
    this time) compiled with gcc7.3.0

    *configure options are:*
    --prefix=/opt/openmpi-GCC73/v3.1.x-20181010'

    '--enable-mpi-thread-multiple
