The virtual table of struct B gets different names depending on the
presence of the forward declaration of struct B in this situation:

struct B;
struct x
{
  friend struct B;
};
struct A { virtual ~A (); };
struct B : virtual A {};

If the forward declaration is present, the following names are
generated:

00000000 t gcc2_compiled.
00000000 t __$_1B
00000060 d __vt$1B$1A
         U __$_1A
         U ___builtin_delete

When the first line is deleted, the following names are generated:

00000000 t gcc2_compiled.
00000000 t __$_1B
00000060 d __vt$B$1A
         U __$_1A
         U ___builtin_delete

When the friend declaration is deleted, the same names as in the first
case are generated, independent of the presence of the forward
declaration for struct B.

This situation occurs in libg++ 2.3 with class istream.
