The default behavior in Gmsh 2.0 is to use "incomplete" second order
elements (8-node quads, 20-node hexas, etc.). Maybe that's causing some
trouble in your code?
You can revert to using "complete" second order elements by unselecting
"Use imcomplete second order elements" in Options->Mesh->General.
