Jan Stránský proposed the following answer:
Hello,
this is a bug, probably coming from a different version of Eigen library in
Ubuntu 16.04. We will try to correct it.

> Hello,
> In the past, I used Ubuntu 14.04 to install YADE(1.07.0) and built a
> model which used material "cpmmat". It worked fine. But now, I used Ubuntu
> 16.04 and install YADE(1.20.0) on it by the same way that using the command
> "sudo apt-get install yade", and use it to run the same *.py code(model).
> It does not work any more. If I use YADE on Ubuntu 16.04 to run the
> concrete example in trunk/examples/concrete, it still work fine. I think
> may be the YADE source code changed(from 1.07.0 to 1.20.0) and my model is
> incompatible with the new one. The error information and my code is
> following. Can you give me some suggestions?
