Issue L61125     [previous patch]

match_list and match_scores over-run
Submitted by: Martin Bays     Appeared in: Library 6/11 or before     Fixed in: -
Problem

The problem is that match_list-->number_matched is being accessed, when match_list has length only number_matched (that is, entries 0..number_matched-1). In particular this causes errors when the match_list is of full length (64 entries). Similarly for match_scores.

Solution

Apply this patch to parserm.h:
