Bug Description

Minimal code example:

from dolfin import *
mesh = UnitSquareMesh(2, 2)

V = VectorFunctionSpace(mesh, "CG", 2)
Q = FunctionSpace(mesh, "CG", 1)
W = V * Q

w = Function(W)
(u, p) = w.split(False)
File("test.xml") << u # Crash!

Issue:

When saving u to the XML file a Segmentation fault occurs.
When replacing w.split(False) with w.split(True) that supposedly uses deep copy instead of shallow copy the problem does not occur.

Environment:
Ubuntu 12.04 64 bit, Dolfin 1.2 from PPA
