yes

the destructor is called "free_method" in Pd-lingo and is set via
class_new() [1].

so you basically would do:

void myclass_free(t_myclass*x) {
   free(x->x_ptr);
}
// ...
void myclass_setup(void) {
  class_new(gensym("myclass"), myclass_new, myclass_free,
sizeof(t_myclass), 0, ...);

}

no magic is involved, thus you have to take care yourselves.
