I'm not sure  exactly what you're looking for.  ptype can tell you  
the class - is that what you want?  e.g.

(gdb) p beta
$1 = {<A> = {_vptr$A = 0x30b0, a1 = 200}, b1 = 201, b2 = 202}
(gdb) ptype beta
type = class B : public A {
   public:
     int b1;
     int b2;

     B(B const&);
     B(B const&);
     B();
     B();
     ~B();
     virtual ~B();
     virtual ~B();
}
(gdb)
