           Summary: Construct from yourself w/o warning
           Product: gcc
           Version: 4.5.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

Simple slip in my program bring to waste the time.

Writing the constructor with arguments of new object bring to crash.
No warnings and deep stillness.

The example to crash:

#include<iostream>
class    B{
public:
    int    x;
};
class    A{
public:
    B&    b;
    A(B&x):b(x){}
};
int    main(void){
    A    a(a.b);
    std::clog<<"a.b.x="<<a.b.x<<std::endl;}
