 Hi,
 
 this is a reduced testcase:
 
 ////
 #include <iostream>
 using namespace std;
 
 int main()
 {
    ios::sync_with_stdio(false);
 
    char c;
 
    cin.get(c);
    cout.put(c);
 
    return 0;
 }
 ////
 
 What happens with current mainline is that a <newline>
 doesn't end the get, whereas this happens with the 'sync'.
 
 Therefore, the issue seems more than vaguely related to
 the obnoxious libstdc++/6745 and all that...
 
 Ciao, Paolo.
