debian sid and ubuntu
 

Dear all,

I have debian sid and gcc 4.6.2-4 and libstdc++ 4.6.2-4, and i compile
following program:
/////////////////
#include <iostream>
using namespace std;
struct x{
int x;
int y;
};
int main(){
struct x *p;
cin >> p->x ;
int e;
cin >> e;
return 0;
}
/////////////////////////////////
When i run it under debian sid, i get segmentation fault for cin >>
p->x, but when i compile it under ubuntu, i run it without error.
What's problem under debian? (i like debian....)
