P.P.S. I ran the same test with OpenMPI 1.5.4, the behaviour is the same.

P.S. I have tested with OpenMPI 1.4.5rc4 and the problem is still there.

Hi
I have a strange problem with MPI_Barrier occurring when writing to a
file. The output subroutine (the code is in FORTRAN) is called from
the main program and there is an MPI_Barrier just before the call.
In the subroutine
1. Process 0 checks whether the first file exists and, if not, -
