Error with map<string, vector<vector<string> > >

Visual C++ General

Gregory J.

I've a problem with this code:

#include <iostream>

#include <vector>

#include <map>

#include <string>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])

{

vector<string> vs;

vs.push_back("Hello");

vector<vector<string> > vvs;

vvs.push_back(vs);

map<string, vector<vector<string> > > m;

m["key"] = vvs; // error

return 0;

}

The compiler doesn't show errors, but when I execute it in debugging I see that m contains an error message.

Does somebody know where the problem

Thank you

Probably the Visual Studio Debugger is not yet able to display such complex data type. But the map contains a good value. In order to check, add this line:

const vector< vector< string > > & vvs1 = m["key"];

The value of vvs1 will be displayed correctly.

I think this debugger problem can be reported to Microsoft at http://connect.microsoft.com/VisualStudio/feedback.

AFAIK, the code has no problem. The code has been successfully compiled and executed in the Dev C++. Probably the bug of Visual C++.

Sample code:

int main(int argc, char* argv[])
{
vector<string> vs;
vs.push_back("Hello");
vector<vector<string> > vvs;
vvs.push_back(vs);map<string, vector<vector<string> > > m;
m["key"] = vvs;
cout<<m["key"].at(0).at(0);
system("PAUSE");
return 0;
}
