[Bug libstdc++/33000] cin and hex input (==8 digits gets rejected)

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2007-08-06 04:56 -------
If I add a check for errors:

#include <iostream>
using namespace std;

int main() {
 cout
 << "Input in hex two integers x and y." << endl;
 int x, y;
  if(!cin)
   cout << "error" << endl;
  cin >> hex >> x >> y;
  if(!cin)
   cout << "error" << endl;
  else
    cout << "y: " << y << "x: " << x << endl;
}


----
Then I get this behavior:
Input in hex two integers x and y.
aaaaaaaa
error

If I enter less than 8 digits, it gets accepted.
