Prior to introduction of modifications in rsassa_pss functions related to padding verification, doing a pass to reduce memory consumption of function by replacing memory copies of parts of const buffer by pointers to the original buffer (masked_db and h are subparts of msg buffer which is declared const, salt is a subpart of db which is a working buffer, unmodified after being filled). New pointers scope is limited to the function where they are declared (not returned to caller by any mean), zeroing risk of memory fault related to the change.
