If the two versions of libstdc++ were compiled with the same
version of g++, and were configured exactly the same way, and you
are on one of the "sane" platforms (i.e. not on AIX or Win32), then
you are lucky, and dynamic loader will simply never reference any
symbols from the "second" libstdc++.

Otherwise, all bets are off.

You might want to inject some sanity, by simply removing libstdc++
from the "second" location.
