Debugging missing vtables

On some large application (not written by me), GCC 4.0 does not emit
some vtables, and link errors are the result.

If I understand things correctly, a certain member is deemed the
controlling member, and the vtable is emitted in the translation unit
which contains this member.

Is there a way to cause GCC to print this member?  I think this would
help me to debug this issue.  (It's probably a bug in the application,
but I'm not completely sure.)
