finalizers and dynamic modules

[Jess Balint]

Hi!

Dynamic modules are really cool so far, but I think finalizers should not be mandatory (alloc.c):

#ifdef HAVE_MODULES

     else if (mblk->markers[i].m.u_any.type == Lisp_Misc_User_Ptr)

{

 struct Lisp_User_Ptr *uptr = &mblk->markers[i].m.u_user_ptr;

 uptr->finalizer (uptr->p); <----- should NULL-check first

}

#endif

thanks.
