Did you install gcc 2.95.2 with --prefix=/usr?  If not, it looks like
you're getting your program linked with the shared library installed
as part of GCC 2.95.2, but, at run-time, it's using the library
installed as part of the libstdc++-2.96 RPM.  I wonder why they have
the same SONAME, given that they aren't binary-compatible...

Point LD_LIBRARY_PATH at the directory containing the libstdc++ shared
library installed with GCC 2.95.2, or, when linking programs against
that library, use the -Wl,-rpath,directory link switch so that the
program will know where to find the library it needs.
