Assuming MATLAB was compiled with any version other then the one
you have, what you are doing (runtime-linking together code compiled
with different versions of g++) has undefined behavior.

If you use the "stock libstdc++", MATLAB itself will likely stop
working (because now it will get gcc-3.2.3's libstdc++.so.5 instead
of the one it is expecting).

There is just no way you can safely link together code compiled
by different versions of g++.
