No subject

between the library and the header file.  Either the library is
mis-compiled or the header files are mis-installed.  In either case,
something got botched during the build and installation procedure.  It is
also possible that during the 'restoration' process, multiple libstdc++.so
files are created on the path.  Thus, the wrong one is used.  Try
compiling your sample code with -v option to g++.  This should print out
the paths that are used during the build and link phases.  This will tell
you if the build is using the wrong files.  If you send me the output of
the compile and link, I can comment whether they are correct.
