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!
