Thanks for your bug report. This is a known defect of the vtable
thunks approach (which is default on Linux). A patch is a available at

http://gcc.gnu.org/ml/gcc-patches/2000-02/msg00111.html

[For some reason, the original message to gcc-patches was lost - at
 least it is not in the archives, so I resent it]
