You also get the same result without Python:

(gdb) p p
$1 =3D (Derived *) 0x5d20c0
(gdb) p pb
$2 =3D (Base *) 0x5d20c0
(gdb) p pb2
$3 =3D (Base2 *) 0x5d20d0
(gdb) p dynamic_cast<Derived*>(p)
$4 =3D (Derived *) 0x13f4e8800 <vtable for Derived+16>
(gdb) p dynamic_cast<Derived*>(pb)
$5 =3D (Derived *) 0x13f4e8800 <vtable for Derived+16>
(gdb) p dynamic_cast<Derived*>(pb2)
$6 =3D (Derived *) 0x13f4e8800 <vtable for Derived+16>
(gdb) p dynamic_cast<Base*>(p)
