I went through the procedure of compiling and running, then copied the procedure verbatim from the command line (see below).
[tstitt@memtfe] /pscratch/tstitt > more mpitag.f90
program mpitag
use mpi
implicit none
integer :: err
call MPI_INIT(err)
print *,MPI_TAG_UB
call MPI_FINALIZE(err)
end program mpitag
[tstitt@memtfe] /pscratch/tstitt > mpif90 --version
ifort (IFORT) 12.0.2 20110112

[tstitt@memtfe] /pscratch/tstitt > mpiexec --version
mpiexec (OpenRTE) 1.4.3
[tstitt@memtfe] /pscratch/tstitt > mpif90 -o mpitag mpitag.f90
[tstitt@memtfe] /pscratch/tstitt > mpiexec -n 2 ./mpitag

I am unable to replicate this problem with a 1.4 build with icc.
Can you share your test code?

Hi all,
I was experimenting with MPI_TAG_UB in my code recently and found that its value is set to 0 in my v1.4.3 and v1.4.5 builds (these are the only builds I have available to test).
Oddly it only happens with my builds compiled with the Intel compiler. The PGI builds do produce a non-zero value. Has anyone else experienced this?
Regards,
Tim.
