After the commit 738da36d1b61e5b2a38e5775b23edd214ad88d6e, a bug run well before has been fixed in it. In my env, function ivy--re-filter's args re a string, and candidates a list(number). They will be called with string-match-p. But they are string and number. So error will ignored with ignore-errors function. Just like nothing has been filtered. But the fix has not considered string-match-p. Maybe the question is only caused by my env's setting.
