[petsc-users] Segfault in DMPlexDistributeFieldIS with -log_view

[Adrian Croucher]

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

I'm running the master branch.

Any clues?

- Adrian
