 Have you tried using dwarf-2 debugging?  My understanding is
 that dwarf-2 debugging is generally preferred for C++ debugging.
 In a couple of quick tests, compiling your source with -gdwarf-2
 produced what look like expected results.  The following is using
 gcc 2.95.1 and gdb 4.18.  I have had similar results with gcc 2.93,
 gcc 2.96 and gdb 5.0.
 
 (gdb) b main
 Breakpoint 1 at 0x200127c: file main.cc, line 33.
 (gdb) run
 Starting program: /tmp/main.gdwarf-2
 Breakpoint 1, main () at main.cc:33
 33      A a;
 (gdb) n
 34      B b;
 (gdb) n
 35      }
 (gdb) ptype a.d_i
 type = class I {
   public:
     int d_v;
 
     I & operator=(A::I const &);
     I(A::I const &);
     I(void);
 } *
 (gdb) ptype b.d_i
 type = class I {
   public:
     double d_v;
 
     I & operator=(B::I const &);
     I(B::I const &);
     I(void);
 } *
 (gdb)
