Wrapping problem and memory leak with facet domains in PyDOLFIN

[Martin Sandve Alnæs]

In [1]: from dolfin import *
In [2]: mesh = Mesh("mesh.xml.gz")

In [31]: fd = md.facet_domains(mesh)
In [34]: fd?

Docstring:
    Swig object carries a C/C++ instance pointer

In [35]: print fd

In [37]:
Do you really want to exit ([y]/n)?

I suspect the mesh is the same as in bug 860595, but could you post the mesh
here too?

Also can you please hand a runnable code. I only see snippets. What is a md?

Sorry, cut too much...

md = mesh.domains()

Don't have time to give you more right now.
