shared_ptr only uses typeid(T), where T is a type, so it works on some compilers with RTTI off. But not on GCC. You need to replace the bodies of the two functions with 'return 0;' to make it compile. Of course you wouldn't be able to use get_deleter with this modification, but everything else should work.
