I've tracked a leak in the Python interface down to the line:

  # Initialize base class
  cpp.Form.__init__(self, self._compiled_form, self.function_spaces,
self.coefficients)

on line 46 of form.py. If I do

  cpp.Form.__init__(self, self._compiled_form, self.function_spaces, [])

then there is no observable leak. Any ideas? I checked dolfin::Form it
it looks ok. I even commented out all code in the dolfin::Form
constructor to be sure.

Below is the script that I've been testing with.

from dolfin import *
parameters["form_compiler"]["cpp_optimize"] = True
parameters["form_compiler"]["optimize"] = True
mesh = UnitSquare(16, 16)
for t in xrange(20000):
    for level in xrange(100):
        V  = FunctionSpace(mesh, "CG", 1)
        v  = TestFunction(V)
        u  = Function(V)
        u0 = Function(V)
        L = v*(u-u0)*dx
        b = assemble(L)
    print "----"
