You can try with the master repo to see if this fixes your issue.

I checked and I actually using version 1.8.0 updated.
The strange thing, that lead me to think that there is something wrong with memory allocation, is that if I change, for example, print content, it change systematically the output, even if truncated to int, so it is not a problem with float management, but maybe some register or ram that is overwrited or bad instantiated?

Try print to console first
