It's OK, I found the problem.
I was accidentally passing in a DM which hadn't been created yet. This
didn't matter when not using -log_view, because it looks like the DM
isn't actually used for anything else inside DMPlexDistributeFieldIS().
But when you run with -log_view it tries to get its communicator.

hi
My code is using DMPlexDistributeFieldIS() to distribute an index set,
and it seems to work ok, except if I run with -log_view.
In that case I get the error below.
The code (Fortran) looks like this:
call PetscSectionCreate(PETSC_COMM_WORLD, dist_section, ierr)
CHKERRQ(ierr)
call ISCreate(PETSC_COMM_WORLD, dist_index_set, ierr)
CHKERRQ(ierr)
call DMPlexDistributeFieldIS(self%dm, sf, section, &
index_set, dist_section, &
dist_index_set, ierr); CHKERRQ(ierr)
call PetscSectionDestroy(dist_section, ierr); CHKERRQ(ierr)
call ISDestroy(index_set, ierr); CHKERRQ(ierr)
index_set = dist_index_set
