Hi,
I am having a problem where ferret.so is crashing which highlighting
search results. The query string is
"25,42,53,80,88,119,135,139,389,445,464,563,593,636,1441,1442,1444,1515,
1519,1527,1537,1546,3389". In the debugger I can see that the crash
happens in search.c on line 907. The reason is that the excerpt->end
field is -1. I think the reason is because in this code from search.c:
for (e_start = e_end = 0; e_start < mv->size; e_start++) {
const int start_offset = matches[e_start].start_offset;
if (e_start > e_end) {
running_score = 0.0;
e_end = e_start;
}
while (e_end < mv->size &&
(matches[e_end].end_offset
<= start_offset +
excerpt_len)) {
running_score += matches[e_end].score;
e_end++;
}
pq_push(excerpt_pq,
excerpt_new(e_start, e_end - 1, running_score));
/* - 0.1 so that earlier matches take priority */
running_score -= matches[e_start].score;
}
e_end is never being incremented beyond 0, so e_end-1 is stored as the
excerpt. However I am not sure why that is.
Anyway, thought this bug report might be useful.
