When petsc4py is installed, the mpi_comm_world-function returns a
petsc4py.PETSc.Comm-object. I guess this is true for all MPI communicators.
When writing an extension module using a MPI_Comm as argument, this fails.
MWE:
*from dolfin import *cpp_module="""void foo(MPI_Comm comm)
{}"""compiled_module =
compile_extension_module(cpp_module)compiled_module.foo(mpi_comm_world())*
I guess this is related to this:

Any way to work with this?
