Title:
broken transform_data on refine
Status in DOLFIN:
Fix Released
Bug description:
I've realized that somewhere during last year refinement features has
been broken. Not whole refinement, but only the part responsible for
MeshData transformation between old and new mesh. This is code was
written by me, so I'll try to fix it, but maybe some of you guys can
take a quick look and help me which recent change could cause this
problem.
===== Code to repeat crash =====
#include<dolfin.h>
using namespace dolfin;
int main(){
UnitCube mesh(10, 10, 10);
mesh.data().create_mesh_function("material indicators", 3);
MeshFunction<bool> mf(mesh, 3);
mf = true;
Mesh newmesh;
newmesh = refine( mesh, mf);
}
===== Error messages =====
Refining simplicial mesh by recursive Rivara bisection.

dolfin::MeshFunction<T>::operator[](dolfin::uint) const [with T = unsigned
int]: Assertion `index < _size' failed.
