Followup-For: Bug #1088865
All of the MESHITERATOR_MACRO functions in python/src/mesh.cpp are
affected (cells, facets, faces, edges, vertices)
so I guess the problem is somewhere in MESHITERATOR_MACRO:
#define MESHITERATOR_MACRO(TYPE, NAME) \
py::class_<dolfin::MeshEntityIteratorBase<dolfin::TYPE>, \
std::shared_ptr<dolfin::MeshEntityIteratorBase<dolfin::TYPE>>> \
(m, #TYPE"Iterator", "DOLFIN "#TYPE"Iterator object") \
.def(py::init<const dolfin::Mesh&>()) \
.def("__iter__",[](dolfin::MeshEntityIteratorBase<dolfin::TYPE>& self) {
self.operator--(); return self; }) \
.def("__next__",[](dolfin::MeshEntityIteratorBase<dolfin::TYPE>& self) { \
self.operator++(); \
if (self.end()) \
throw py::stop_iteration(""); \
return *self; \
}); \
\
m.def(#NAME, [](dolfin::Mesh& mesh, std::string opt)
\
{ return dolfin::MeshEntityIteratorBase<dolfin::TYPE>(mesh, opt); }, \
py::arg("mesh"), py::arg("type")="regular"); \
m.def(#NAME, [](dolfin::MeshEntity& meshentity)\
{ return dolfin::MeshEntityIteratorBase<dolfin::TYPE>(meshentity); })
