<pre>Hi!
It is my understanding than in C++11, contrary to C++98, the following program
has a well defined behavior, and I should get what I have put back in the
stream:
$ cat /tmp/foo.cc
#include <iostream>
#include <sstream>
#include <string>
int main()
{
std::istringstream i{"a"};
int c = i.get();
std::cerr << c << '\n';
i.peek();
i.putback('A');
c = i.peek();
std::cerr << c << '\n';
}
$ clang++-mp-3.7 -std=c++14 /tmp/foo.cc
$ ./a.out
97
-1
$ clang++-mp-3.3 -std=c++11 /tmp/foo.cc
$ ./a.out
97
-1
Please, note that if I use unget instead of putback, I get the expected
behavior.
Cheers.</pre>
