This does only alter the str representation of a form. As far as I am
conserned is this not used anywhere. It is the repr of a form that is
used. This is not changed.

I am closing this

Bug description:

The representation of a form changes somewhat erratically when the same code is run multiple times 

Cf:

{ v_0 * <Function in <Function space of dimension 9 (<CG1 on a <triangle of degree 1>>)>> } * dx0
{ v_0 * w_0 } * dx0

as output from:

from dolfin import *

for i in range(2):

    mesh = UnitSquare(2, 2)
    V_h = FunctionSpace(mesh, "CG", 1)
    f = Function(V_h, "1.0")
    u = TrialFunction(V_h)
    v = TestFunction(V_h)
    a = inner(grad(v), grad(u))*dx
    l = dot(v, f)*dx
    pde = VariationalProblem(a, l)
    print pde.L.form_data.form
