False positive [containerOutOfBounds] with std::map<int, >

[Ruud Althuizen]

When using a std::map with int for the key the bounds are checked as if it's an array. Tested on 2.8.

std::map<int, std::string> myMap = {
  {1, "1"},
  {2, "2"},
  {3, "3"},
  {4, "4"},
  {5, "5"}};

for (int i = 1; i <= 5; ++i)
{
  // Out of bounds access in 'myMap.at(i)', if 'myMap' size is 5 and 'i' is 5
  int myInt = myMap.at(i);
}
