Public bug reported:

The warning

  swig/python detected a memory leak of type 'dolfin::CellFunction<
dolfin::uint > *', no destructor found.

is printed printed when a function that returns a CellFunction<uint> is
called from the Python interface. The below program reproduces the
error.

  from dolfin import *

  if not has_trilinos():
      print "DOLFIN has not been configured with Trilinos. Exiting."
      exit()

  mesh = UnitSquare(4, 4)
  coloring = CellColoring(mesh)
  colors = coloring.compute_local_cell_coloring()
