This may be more Ritual Incantation than reasoned action, but I
believe you also need to make sure to call unprotect/protect when you
assign a new value to the C struct slot:

struct foo {
   SCM bar;
};

[...]
   SCM  new_val;
   foo  * bax;
   
   /* scm_protect_object should have been called in the initializer
    * for 'bax' */ 
   scm_unprotect_object(bax->bar);
   bax->bar = new_val;
   scm_protect_object(bax->bar);

b.g.
