--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Could you clarify exactly what you think is a bug then?
This example shows that failbit is set on the output stream, as required:
#include <fstream>
#include <iostream>
#include <sstream>
int main()
{
std::ifstream f(".");
std::ostringstream ss;
ss << f.rdbuf();
std::cout << (bool)f.fail() << '\n';
std::cout << (bool)ss << '\n';
}
The standard doesn't say anything about operator<<(basic_streambuf<C,T>*)
setting any error bits on the input streambuf if reading characters from it
fails.
