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.

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

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);
}
