If this occurs to you, add \texttt{-fabi-version=0} to your custom
compiler flags. In interactive mode, this is done via the Compiler
Menu, as described in Section~\ref{sec:compiler-menu}. Afterwards
rebuild the libraries.
If this occurs to you, please seriously consider upgrading your
compiler. This issue is fixed starting from \Gcc{3.3.1}.
Alternatively, you can add \texttt{-fabi-version=0} to your custom
compiler flags\footnote{Thanks to Christopher Intemann for pointing

as described in Section~\ref{sec:compiler-menu}. Afterwards rebuild
the libraries. But note that changing the \textsc{Abi} might have side
effects. Hence, a compiler upgrade is the recommended fix here.
