memleak in map

[adapanaidu]

 #include <iostream>
#include <map>
using namespace std; 
 
int main()
{
	map < int , string > sampMap;
	map < int , string > sampMap1;
	sampMap[1] = "Adams";
	sampMap[2] = "Peter";
	map < int , map< int , string >> tempMap;
	tempMap[1] = sampMap;
	sampMap1 = tempMap[1];
	sampMap1[3] = "Thomson";
	tempMap[1] = sampMap1;
}

Will this program cause any memory leak?
As we are assigning( over writing ) sampMap1 to tempMap[1], will the tempMap loose the reference of sampMap and produce any memory leak?
