[C++] STL map 전역변수

전역 변수로 map을 선언하고 초기화하는 코드가 컴파일이 안되더군요.
#include <string>
#include <map>
using namespace std;
map<int, string> intStrMap;
intStrMap[1] = "hello";
intStrMap[2] = "world";
int main()
{
return 1;
}

맵에 내용을 넣는 부분을 함수 안으로 옮기면 잘 되네요.
#include <string>
#include <map>
using namespace std;
map<int, string> intStrMap;
int main()
{
intStrMap[1] = "hello";
intStrMap[2] = "world";
return 1;
}
왜 이런 것인가요?
