cppcheck 2.10 False Positive (containerOutOfBounds) with array of functions

[penguish]

False positive for array index out-of-bounds when dealing with postincremented index on an array of functions, e.g.

#include <iostream>
#include <array>
#include <functional>

int main(int argc, const char * argv[]) {
  unsigned roiElementNumber = 0;
  //
  std::array<std::function<int(const int)>,2> fillResultFunctors={
    [&](const int n) { return n;},
    [&](const int n) { return 100+n; }
  };
  constexpr std::array<int,3> a{1,2,3};
  //cppcheck gives false containerOutOfBounds error
  for(const auto i:a) {
      if (roiElementNumber > 1) { 
        roiElementNumber = 1; 
      }
      std::cout<<fillResultFunctors[roiElementNumber++](i)<<'\n';
  }
  std::cout<<'\n';
  //cppcheck is ok with this
  roiElementNumber=0;
  std::array<int,2> b{100,200};
  for(const auto i:a) {
      if (roiElementNumber > 1) { 
        roiElementNumber = 1; 
      }
      std::cout<<b[roiElementNumber++]<<'\n';
  }
  return 0;
}
