Subject: Re: Extension module: Why does object get GCed?

I tried adding ruby_obj to a stl vector. This doesn't work and the
object is still freed.

The following code works, but is ulgy as hell (and leaky :)

class RefHolder {
public:
	VALUE val;
};

void BindToRubyVariable(someObject* native, char* variableName) {
  ...
 RefHolder* r = new RefHolder();
 r->val = Data_Wrap_Struct(klass, 0, 0, native);
 rb_define_variable(variableName, &(r->val) );

} 

Any better ideas?
