[Bug c++/18113] New: compiler allows 2 copy constructors

[profvonsully at yahoo dot com]

The bug is simple : 
 lets say : 
  
" 
 class TObject; 
 typedef TObject& rObject; 
 class TObject 
 { 
 public: 
 TObject(){} 
 TObject(const TObject&); 
 TObject(const rObject); 
 }; 
  
 TObject::TObject(const TObject&) 
 { 
 char*s; 
 s="constructor 1"; 
 }  
  
 TObject::TObject(const rObject) 
 { 
 char*s; 
 s="constructor 2"; 
 } 
" 
In da function: 
" 
TObject F() 
 { 
 TObject AnObject; 
 TObject anotherObject=AnObject;//constructor 2 !!! 
 return AnObject; 
 }  
  
" constructor 2 will be called!

there is another example for those that did not look at the attachment(sorry 
for my initial language): 
 
class TObject; 
 typedef TObject& rObject; 
 class TObject 
 { 
 public: 
 TObject(){} 
 TObject(const rObject){}//the compiler does NOT realize that this is 
a copy constructor 
 //TObject(const TObject&){} the compiler wants this to be a copy 
constructor  
 //   "error: no matching function for call to 
`TObject::TObject(TObject)'" :))) 
 //I am [EMAIL PROTECTED] 
 }; 
  
 TObject GetAnObject() 
 { 
 TObject AnObject; 
 return AnObject; 
 } 
  
 void HandleObject(TObject toj) 
 { 
 } 
  
 void errors_are_here() 
 { 
 HandleObject 
 ( 
 GetAnObject() 
 );/*here g++ says an error exists*/ 
 }

(In reply to comment #7 
i dont care about the const . i descovered the bug in the first example of the 
attcahment where the compiler prints an error that is not logic(in borland C++ 
i used TObject(rObject) with no problem). 
If a fuction returns a TObject and I pass the result to a function that 
receives a TObject an error ocurs !! pls make me understand this :)

!!!  
in the second example only one constructor is writeed (to be compiled) 
"TObject(rTObject)"!!(the other one is in a coment and ... errror)
