Is a private destructor allowed here?

[Joost Kraaijeveld]

GCC 3.3.1 allows the following code, Borland C++ 6 gives an error. I have
looked in the standard but could not find the answer. Should this code
compile, given that the private destructor (and constructor but there
Borland does not give an error) is called in the public static function:

class Object
{
public:
static Object& getObject()
{
static Object o;
return o;
}
private:
Object(){}
~Object(){}
};

int main()
{
Object& o = Object::getObject();
return 0;
}

TIA

return 0;
}

Nothing is wrong with the code. Since 'getObject' is a member,
it has access to all members of the class, private constructors
and destructors included.

When you say Borland C++ 6 do you mean C++ Builder 6 or the new
Borland C++ compiler version 6? If the later, you should report this
to Borland.
