[Bug libstdc++/25649] [4.2 regression] Bogus "uninitialized" warning

[pinskia at gcc dot gnu dot org]

------- Comment #9 from pinskia at gcc dot gnu dot org  2006-01-24 17:14 -------
Here is an example of where we get a false postive:
#include <iostream>

using namespace std;

int main()
  {
  int x;
  cin >> x;
  if (!cin)
  {
    x = -1;
  }
  cout << x << endl;
  }

We check the error status of cin after "cin >> x"  has run and if that fails we
set x to -1 but the warning still shows up.
