This comes from the new type checking for Fortran code.
I suggest you just call MPI_Barrier() using MPI_COMM_WORLD from Fortran.

First I would add -gamg_est_ksp_type cg
You seem to be converging well so I assume you are setting the null space
for GAMG.
Note, you should test hypre also.
You probably want a bigger "-pc_gamg_process_eq_limit 50". 200 at least but
you test your machine with a range on the largest problem.
please respond to petsc-users.
You are doing 5 solves here in 14 seconds. You seem to be saying that the
two pressure solves are taking all of this time. I don't know why the two
solves are different.
You seem to be saying that OpenFOAM solves the problem in 10 seconds and
PETSc solves it in 14

This is standard mailing list etiquette. It is important to preserve
