I think you can just do:

    diff --git a/src/alloc.c b/src/alloc.c
    index 6e166d00d5b..acf558f3c7a 100644
    --- a/src/alloc.c
    +++ b/src/alloc.c
    @@ -5611,7 +5611,8 @@ DEFUN ("purecopy", Fpurecopy, Spurecopy, 1, 1, 0,
     static Lisp_Object
     purecopy (Lisp_Object obj)
     {
    -  if (FIXNUMP (obj)
    +  if (true
    +      || FIXNUMP (obj)
           || (! SYMBOLP (obj) && PURE_P (XPNTR (obj)))
           || SUBRP (obj))
         return obj;    /* Already pure.  */

But, the "pinned" approach as is done for hash-tables should work just
fine as well.
