It also uses that increased value as the limit for\nparsed predicates. If the initial count is smaller than the number\nactually parsed, the program can fill the allocation and subsequent\naccesses can go past its end.\n\nKeep nr_preds as the predicate limit and use a separate value for the\nallocation size. This leaves space for both terminal entries and a\nzeroed entry when parsing stops at the limit."
