See the "testing multi-abi binaries" section at the bottom:

A "C" application, dynamically linked to two shared libraries, liba, libb. The
dependent library liba is C++ shared library compiled with gcc-3.3.x, and uses
io, exceptions, locale, etc. The dependent library libb is a C++ shared library
compiled with gcc-3.4.x, and also uses io, exceptions, locale, etc.

[ ... snip ... ]

This resulting binary, when executed, will be able to safely use code from both
liba, and the dependent libstdc++.so.6, and libb, with the dependent libstdc++.so.5.

A C++ program linked indirectly (via a C library) against another C++ library is
exactly the same scenario. This is the whole point of symbol versioning.
