           Summary: forward declaration error
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: kemin dot zhou at ferring dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux
  GCC host triplet: i686-pc-linux
GCC target triplet: i686-pc-linux

when two classes have inter dependency, compiler could not compile.
The exact same code can be compiled with no problem with gcc3.2.2
After upgrading to gcc3.3.1, the same code would not compile:

the basic class lay out is like this:
class B;   // the forward declaration, stopped working in 3.3.1
class A {
  vector<B> bvec;
};
class B {
 public:
  void method(A& a);

   private:
      int someMembers;
};

The code you give is incomplete, and you also didn't give the exact command line 
to compile it. We can't do much without this information. Please review 
  http://gcc.gnu.org/bugs.html 
to see what we need. 
 
In any case, your code may not be valid. A similar problem is discussed in PR 10505, see 
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10505

I am just going to say this is a dup of bug 10505 from the comments.
