Hi, Luigi
Thank you very much for your report and my apologies for delay of the answer.
It's good to know that they are appreciated. Zooming out, I'm not sure I think that the variable arrays of parameters are a good idea. The original idea was to be both flexible and memory-efficient, but by modern standards the amount of memory is miniscule, and the arrays don't do the readability of the code any good. I will probably drop them in favuor of regular struct member variables. I may be wrong, so if you or anyone else have convincing arguments in favour of the arrays, I look forward to hearing them.
We are currently quite busy but there should be a debugging session at the end of current month, and we will see this issue as the others as well.
Good luck! I have already applied local fixes, so don't feel any pressure on my behalf. /Lars
