Most likely your program t is using the libstdc++.so which comes with the system rather than the libstdc++.so which is part of your newly installed gcc. This can happen if you configured gcc with a --prefix option. The simple fix will be to set the LD_LIBRARY_PATH environment variable to point to the directory holding your libstdc++.so. Ian
