 Well in my case you need to write

   void tt()
   {
       char i;
       VALUE obj;

       obj = rb_str_new2("a string");

       /* call some ruby functions which call the GC */

       i = RSTRING(obj)->ptr[0];
   }

   int main(void)
   {
       ruby_init();
       ruby_init_loadpath();
       tt();
       return 0;
   }

 Now the GC will see `obj' on the stack and will mark the string.

 The problem with my example

   int main(void)
   {
       char i;
       VALUE obj;
       VALUE klass;

       ruby_init();
       obj = rb_str_new2("a string");
       /*  etc */

   }

 is that ruby can't see that `klass' and `obj' are on the stack and it will
 not be marked by the GC.
