You're right, I had overlooked this.

I'm working on a fix for the next release. For now, simply replace 
QP_PARTIAL_DANTZIG by QP_BLAND in the file Polytope_distance_d.h. If 
you're calling the package as in the example file 
polytope_distance_d.cpp (full exact computations), this should solve the 
issue. If you call it as in polytope_distance_d_fast_exact.cpp (filtered 
computations), you should switch to full exact computations.

Best,
Bernd.
