If you can target Tiger/gcc 4.0, another way of dealing with this is
to invoke the gcc flag:
-fobjc-call-cxx-cdtors
Look for "Call C++ Default Ctors/Dtors in Objective-C" in your Xcode
build settings. It's description is:
Run non-trivial default constructors and destructors on C++ instance
variables of Objective-C classes.
