[Bug c++/40293] New: reference can be initialized by itself

[pentek dot imre at gmail dot com]

At this code I was able to initialize the reference by itself, so actually it
became an uninitialized reference:

#include 

using namespace std;

class t
 {
  public:
   t():x(x){x=0;cerr

The same applies to this code:

#include 

using namespace std;

int main()
 {
  int &x=x;
  x=0;

[Bug c++/36866] New: lack of warning when initializing a class member from an uninitialized variable

[pentek dot imre at gmail dot com]

Hello, the attached code compiles without any warning when compiled with the
command
g++ -W -Wall any.cpp -c -o any.o
but x gets initialised from itself, actually dereferencing x prior to
initializing it. At this point it is trivial that x wasn't initialised.
