Thanks for the feedback!

What application are you attempting to compile?
I am finding some debian based bugs regarding these symbols, but I find them
correctly in the libstdc++.so.6.0.10 library.

$ nm libstdc++.so.6.0.10

I would like to try and duplicate the error so I have a better understanding
of exactly what is going on when the link blows up.  I believe this to be an
upstream bug.

I would like to get the necessary info to fix it and submit the fix upstream.
