Not sure why you don't believe it is the max bounds in this case? Anastasia, the number of regions is initialised to 10 and 16 above but that isn't the *max* bound for the loop.

I am not overly concerned about the identifier name, `max_region_index` or something will do, the structure of the code is more important imho. The main thing here is that the static analyzer is alluding to a area of code that has a possibly overflow generally indicates poor structure that allows such subtle bugs to emerge.
