As far as I remember this is the bug which leads to dummy index renaming and some other changes outside of clifford.cpp. It seems to be difficult (if ever possible) to fix it within the 1.3 branch, hopefully the 1.4 release will follow within a reasonable time. However if one do need my example to run through 1.3 branch then the first version of the code is still available on arXiv.org and should be working with it. Best wishes, Vladimir -- Vladimir V.
