[petsc-dev] Error in PetscSectionCreate using Fortran

[Chris Eldred]

I am getting a segmentation fault when calling PetscSectionCreate. The error is:

[unset]: aborting job:
application called MPI_Abort(MPI_COMM_WORLD, 59) - process 0

The relevant code section is:

call PetscSectionCreate(PETSC_COMM_WORLD, section, ierr)
CHKERRQ(ierr)

call PetscSectionSetChart(section, 0, 11, ierr)
CHKERRQ(ierr)
do p=0,10
 call PetscSectionSetDof(section, p, 3, ierr)
 CHKERRQ(ierr)
end do
call PetscSectionSetUp(section, ierr)
CHKERRQ(ierr)

call PetscSectionView(section, PETSC_VIEWER_STDOUT_WORLD, ierr)
CHKERRQ(ierr)

call PetscSectionDestroy(section, ierr)
CHKERRQ(ierr)

Ideas?
