I don't see anything obvious in the upgrade from 4.1.5 to 4.1.6 that should change behavior of MPI_BARRIER (in Fortran or otherwise). So it's a little suspicious that the problem disappears in 4.1.6.
In a situation where it hangs, can you get stack traces from both MPI processes to see where it's hung?

Well very strange but I can't reproduce it any more. I must have messed up my runtime environment somehow.
The code compiles and runs with v4.1.5
and v4.1.6
.
If I manage to reproduce the error I will reopen and post stack traces.
