[Bug c++/25410] New: poor ostringstream output

[aburger at cea dot fr]

The following code compiles, but the result of the first line of main is poor
(it prints the address of the string):

#include <iostream>
#include <sstream>

using namespace std;

template<typename A, typename B>
basic_ostream<A,B>& tic(basic_ostream<A,B>& o)
{
    return o;
}

template<typename A, typename B>
basic_ostream<A,B>& tac(basic_ostream<A,B>& o)
{
    if( ostringstream* oo = dynamic_cast<ostringstream*>(&o) ) {
        cout << oo->str() << endl;
    }
    return o;
}

int main()
{
    ostringstream() << "tac alone does not give a nice result" << tac;
    ostringstream() << tic << "tic+tac together work" << tac;
}
