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.
