Warning when initializing a vector<pair<>> from a map

This compiles clean, but CLion flags the initializer with an error:

map<string, int> works;
for (string l: {"a", "a", "b", "c"}) {
works[l]++;
}
vector<pair<string, int>> scores{works.begin(), works.end()};

  • Class 'map<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator>, int>::iterator' is not compatible with class 'pair<string, int>' (at line 13)

Is this a bug, and if so is it a known bug? The value type of a map<K, V> is pair<const K, V>, so it should work as far as I can tell.

Thanks.
