>Description:
When I run the following code

#include <iostream>

using namespace std;

int main()
{
	int i;
	cin >> i;
	cout << "i == " << i << endl;
}

cin doesn't wait for input - the cout code gets executed with a random value for i.

I'm using gcc from CVS, updated a few hours ago.

When I run the same code under gcc 2.95.3 it works fine.
