This is a follow-on to task http://www.google-melange.com/gci/task/view/google/gci2013/5345276583739392
Basically, use the information from the suspected cause of the bug, which has been narrowed down to just a few locations in the code, and see if a fix can be devised and demonstrated.
Provide a patch that fixes the permutation, either by changing the g-iges export or the iges-g import (or both if necessary).
